I use about 8 to 1 mix of water with simple green for 5 to 10 mins max with NO heat. That will preserver the coating.... if you go longer it will start removing the coating and the heat discolors everything and is also detrimental to the coating. I put them in a towel and bounce it some to get the b...

Since you cycled them through you are probably good to go but the real proof is when you shoot them and see if anything hangs up. If it hangs pull the mag and inspect if the next round is sitting there in the mag with no real pressure on it. With one thousandths of taper you might see things hang a ...

Sounds like you are doing well!!! If your die is holding the case diameter within a thousandth around 0.311 or 0.312 you should be fine. If it gets up to 2+ thousandths like it did on mine (http://www.fivesevenforum.com/viewtopic.php?f=19&t=2646&start=120" onclick="window.open(this.href);return fals...

Dang - I just hit one of my chrony light-diffuser metal support rods yesterday after about 2 years (turned it into a pretzel).... lucky it didn’t break anything else….

I agree with you guys regarding the claims by these companies and whether you can trust there claims. Being an engineer and working lots of high temperature thermal systems I know the issues that is why I elected to just install the sprinkler head – it will buy you lots more protection and water is ...

Samurai - I agree with fire protection in your case given those experiences (and if you are really worried routing some water over to it is added protection). Industrial is an excellent descriptive word for them... you sure can't hurt the thing. I even pulling the door off mine, hauled it into my sh...

I own a Sturdy Safe, a smaller model 2723 which I have had it for about 2 years now - it is extremely well built – I would highly recommend them. It has thick 7 gauge walls and the door recessed with a gap that won't even allow a playing card into it... no way for a pry-bar. It is extremely well mad...

Here is a good one "Choose Your Own Crime Stats"

I agree with f3rr37. I recently had the same itch and just picked up a Rem 700 SPS Tactical AAC-SD and equipped it with a harris bipod, badger ordnance steel rail/scope mounts and a SWFA 3-9x42 scope. It shoots like a dream with good consistency and the price wasn’t that bad for everything. I screwe...

Great job Jay! Did you use HD17 grade material? That puts you at about 1oz increase based on calculations for a square unit - so you hit it spot on!

Have shot my ps90 out to 200 yards with little 30gr vmax bullets - approximate groups: 2” at 100 yards, about 5” at 150 yards and 8” at 200 yards. I used a scope off a bench and would be very interested in what you get as you push it out. http://www.fivesevenforum.com/viewtopic.php?f=19&t=4561" oncl...

My final crimp length is about 0.030" and has worked fine. I think you are good to go!

Here are some interesting ones ...http://www.ar15performance.com/muzzle_devices" onclick="window.open(this.href);return false;

It’s the cylindrical weight in the slot on the side of the bolt. By making it heavier (increasing the inertial mass of the bolt) it cycles slower. This can help for hotter loads allowing the bolt to stay in battery for slightly longer (letting pressure drop off) and reduce the magazine popping issue...

When you are looking, there are also machinable grades HD17.5, 18 and 18.5 which are heavier (1.5gm/cc for the HD18.5). - so by going with your new square design and a heavier alloy you can increase the weight by over an ounce. http://www.mi-techmetals.com/hd-typical.htm" onclick="window.open(this.h...

I was finally able to confirm today that the PS90 rate reducer is made of machinable Tungsten HD17 (at 17gm/cc). I took the reducer out of my PS-90 and tested it on a Bruker XRF spectrometer (http://www.bruker-axs.com/handheldx-rayspectrometry.html" onclick="window.open(this.href);return false;) at ...

Sounds like a good plan! If I remember from the other threads the bee FCD might have issues with hitting the case shoulder if it is shortened too much - so move up on it slowly and stop when you get a good looking crimp. Good luck!

I used a 22 hornet FCD as the starter for modification and my shell holder is a hornady. My final collet length was 1.075" which gave me about 20 to 30 thousandths on the crimp. Since you are using a different FCD start by sticking a resized/trimmed piece of brass in the shell holder and measure the...

I did a quick calculation assuming your reducer dimensions of 0.557”x0.557”x1.185” with a hole down the center that I assume is a 0.32” diameter. If I assume ~8gm/cc for the stainless steel it comes to 1.26 oz about 0.4oz lighter than the factory 1.66oz bounce weight so that is in fairly good agreem...

I just pulled my PS90 stock bounce weight and weighed it at 47.2 gms. From the measurements I just took on it (OD= 14.2mm, ID=8.13mm L= 26.04mm) it comes out to 2.78 cc. The stock density is then 47.2/2.78 (gm/cc) = 16.97 gm/cc. This is ~2x the density of stainless steel and very close to the machin...

Here is my PS90 (pictures looking forward and reward on the latch hole). I have about 2000+ rds through it. I haven't had any "pop up" issues with any rounds I have fire through it including some of my hotter reloads. Regarding the bounce weight on the bolt, when I was talking to ninthining regardin...

they were suppose to be 1x brass that I got from Scharch (bought 1000) - I posted over on that thread what I was seeing... http://www.fivesevenforum.com/viewtopic.php?f=19&t=6174&start=80" onclick="window.open(this.href);return false; I need to try some of the same loads with my own 1x brass (from S...

iFire, what cartridge length are you using? I loaded mine at about 1.490 to 1.495 and got neck splits with TB at 6, 6.2 and 6.3 gr loads. My velocity at 6.2 is about 40 ft/sec slower than yours.

Let us know what velocities you are getting. I have been using unique on the 9mm and have been thinking about switching to TB (since I have a couple lbs of it). The cases are pretty dirty from the unique - hoping the TB cleans it up some.

Excellent Work!!!

I typically just shoot it and then reload it (more fun) - I know others pull down and reload. That was panzermk2 using the 60X magnification. Maybe you could try reloading and shooting the Scharch brass that survived the first cycle and see how it fairs the second and third time around - maybe you w...

buy some SS197sr factory ammo and then reload it after you shoot it and see what results you get. I have gotten many many reloads out of that brass - the coating starts failing before the neck (but I am not maxed out and usually run about 5.7 or 5.8gr of true blue with the 40gr vmax). I am still not...

What type of brass are you using? I had no issue with neck cracks seperation when reloading the spent factory SS197sr cases. However, I picked up a bunch of Scharch brass cheap and had a number of bad neck cracks and one seperation to date (http://www.fivesevenforum.com/viewtopic.php?f=19&t=6174&sta...

Look at those leaning cartridges! I sent you the info - they should be able to get you taken care of! I have only had a chance to fire about 150 rds since then but my magazine issue seem to have gone away!

Another vote for the 458 socom - I have one and love it! You really need to be a reloaded to own one (due to cost of ammo) but there are lots of bullets to choose from and bulk 300gr and 405gr Rem bullets are dirt cheap.

tparty, Thanks for the info. The pictures are AFTER the first firing of the Scharch cases. The shoulder has moved forward some but not a lot (if you hold the sized and fired cases side by side). The black on them is powder residual but the cases I got were a little rough. I inspected them after resi...

My trim length for the case is 1.135" (I have used this on all my other loads without issue). I did go to the higher side on the cartridge loaded length (20 thousandths longer than Walkalong’s post which was 1.470") - I based my length on the 30gr Vmax's that I experimented with last year.

Has anyone reloaded much of this brass? I bought 1000 cases and just loaded up 20 of them for the first time a couple days ago to develop loads for some 34gr dogtown JHPs. I found that the primer pockets were pretty loose (slipped right in compared to when I reload the SS197SR’s) – about the same fe...

f3rr37 - Thanks!!!

j_parker, That’s the one I have - CSND 2-die set which I sent back in for modification. It is a really nice die setup but the taper drove me crazy! I would recommend you just email/call RCBS and tell them about your issue (send them the link to this discussion) and how it was corrected. I am sure th...

Yeah - that looks really nice! I wish I had taken a picture of what my chamber looked like orginally

Onyx, I think I may have worked mine a little more. It looks very similar but the machine marks are very hard to see and the reflection is pretty clear (I can see the edges of the rifling reflected along the chamber if I look at a shallow angle). I need to get it out and shoot it to see how the bras...

Glad to give you some data - as for the taper in your cases that 3 thousandths will add up to a noticeable tilt and I found in my case they started to bind at ~ 20 cases in the PS90 mag. Hopefully you will have better results than I did on that. I tried to take a picture of the polish job I did on t...

Onyx – I just examined my PS90 and compared the protrusion length of 4 factory to 4 resized cases (using my Hornady die). Factory protrusion: 0.142” 0.142” 0.140” 0.143” Avg = 0.1418” Reized protrusion: 0.130” 0.134” 0.135” 0.136” Avg=0.1338” For a delta of 0.008” So when looking at the seating of t...

It has been awhile - but to make a long story short, the Hornady folks had my resizing die for a few months and after a few discussions they ended up polishing the die to remove the taper which provide a diameter of approximately 0.312” from top to bottom. I resized about 50 cases and they measure a...

That would be great!!!

This is a great topic! If you are going to increase the mass of the bolt by drilling/adding I would recommend replacement with tungsten slugs and sealing them in with JBweld or other tough machinable epoxy.

9th - Once again great work!!! You are a true pioneer!! How do the primers and case look for these high powered rnds any signs of pushing the pressure limit?? It’s really amazes me how much performance and improvements (trigger etc.) their engineers left on the table. I keep coming back wondering wh...

ninth - great info! Where did you talk about the mod you made to the PS90 to kick up the load... I must have missed that one. You have done some really awesome work with this little rifle!

Onyx - you aren't kidding when you mention that the 30grainer's are short - REALLY SHORT :) I didn't know that when I picked up a bunch of them cheap. Only have a couple hundred left and use them for plinking and messing around - they are good for that. Good luck and keep us posted - when I get my s...

I would be very interested in what you find out (with TB powder). I bought a few hunderd of these but haven't had a chance to work up any loads (to busy working up loads for my new 458Socom and a 338ME). I was going to start with what I had worked up for some 30gr loads (http://www.fivesevenforum.co...

9th - Great pictures and contrast to all the snow :) Good Shooting!!! Looks like a very nice range. speaking of global warming (or maybe on the verge of global cooling) - here is a great set of charts which can stir up all sorts of issues (it sure did at work)! http://www.isthereglobalcooling.com/ya...

Sounds like you have a lot of good projects going. Following up on the fin stabilization idea - it would definitely be best in a smooth bore design if you go that way. The rotation of the fins would create large aerodynamic drag (like the spokes on a wheel) proportional to the square of the rotation...

Great info and very interesting bullets (solid brass)! That setup is really quiet!! Definitely post your new bullet design - what type of fins design were you thinking (they may cause drag issues when coupled with the rotation)?

Thanks ninthinning - I got it out and am polishing it up on the wheel (very reflective) - also cleaned up the hammer assembly and put a small dab of rydol grease on the bearing surfaces... I can already tell a difference! I just dropped one of these aftermarket hammer/spring/trigger assemblies ( htt...

ninthinning - I just popped open my PS90 to take a look - how did you remove the metal push rod… it is attached snugly to the trigger assemble (and I sure don’t want to break anything). It does look like the surface is pretty rough on the thing – I could put a pretty good polish on the length of it ...

X-ring - I am using the Hornady Custom Grade New Dimension with zip spindle dies but I have been having an issue with how they resize the case wall (slight taper) which hurts loading the PS90 mags. You can see my last couple posts on the following topic http://www.fivesevenforum.com/viewtopic.php?f=...

I ran a test and was able to load 8x before seeing splits in the shoulders - but I wasn't pushing it that hard (about 5.6gr TB on a 40gr Vmax for those loads).

Good idea f3rr37 – I had some 1x, 2x, 4x and of course the 8x reload cases so I took 10 random re-sized cases from each batch and made measurements - the results show about the same deviation across all the cases. So the Hornady sizing die is very repeatable in its sizing - it’s just got a taper… I ...

As a follow-up to gw45acp & tdevince who posted earlier in this thread about case dimensions after resizing, I now believe that is the issue with my hang ups on the PS90 magazine rather than the degraded polymer coating. It all started last night when I was looking at the coating on some of my 8x re...

Great Work!!!

I have shot my PS90 out to 200 yards at 50 yard intervals (with 50 yard zero) to test some reloads and a ballistics program. It is pretty much point and shoot with that setup if you are not using optics. One day I will redo the test with 40gr bullets and a more stable base to knock down the dispersi...

My daugher counted the 1k batch I got (she just decided it would be fun) and the tally is: 987 = good cases 18 = not usable cases (1 competely crushed to many about 1/2 crushed and a few that looked pretty much burnt entirely black - not sure what the issue is there) 3 = 223 cases 1 = a lead ball ab...

Something occured to me today when I was shooting the PS90. Most of the hang up issues I have noted (even after having reloaded up to 6 or 7 times) are due to feeding from the magazine (ie a round doesn't want to roll) and not ejection from the action. Even with pretty chewed up coating they cycle f...

Just got my 1K today - they look pretty good - a little dirty, but the simple green cycle will take care of that. Had about three 223's mixed in and one 5.7 case that looked like it when thru a 20 ton press (very very flat).

this should keep me going for some time!

Just bought 1000 myself!

Grant - you are correct. I ended up with 16lbs of the H335 a few years ago because it works ok for both 223 and 308 and there was a lot of reload data. When I run out (which may happen sooner than later with the rate my AR10 burns through 308) I am giving thought to using two different powders.

I have reloaded some 40gr BT hornadys in my 223 (AR15 with 16 inch barrel) and got 3550 ft/sec with 28.8gr of H335 (CCI small rifle primer). You should be able to get those little guys really cooking for short range shots! You will probably start running out of volume long before you hit a max...

Grantness - thanks you very much for the information! I think I will hold my charge the same and take the 100 ft/sec hit with my next loads (they are only for plinking).

Carlosrod - looking forward to seeing your range data!

Updated some items and added a few pictures...

I have been searching the forum for comparisons of small rifle vs. small pistol primers. I have been using small rifle primers to date but am about out and can’t find any right now. However, I do have a couple 1000 small pistol primers on hand. What is the general consensus – at the same powder char...

I ran some quick rough ballistics for your subsonic 55gr (using 1000 ft/sec, BC=0.27, scope height above barrel = 4” and zeroed at 50 yards).

MO – you aren’t kidding about the minimal flash from the PS90, I shot it about a dozen times at dusk and you could see nothing. Thanks for the info. Next time I buy powder I will pick up one of those and give it a try. I like the idea of a plastic/rubber bullet which might have just enough oomph to ...

If one wanted to get a nice large muzzle flash (just for kicks) are there any safe loads out there that can achieve that? When I was shooting the other evening I thought it would be kinda cool if it could light up things for a couple fun shots

I should have added I am using a PS90....

It was a beautiful day - couldn't have asked for better and when we finished up at about 7:00 we cooked out and then shot off fireworks with the kids until about midnight! I agree the trigger is the real problem on the PS (just like the CX4 Storm) out past the 50/100 yard range - the 5.7 round does ...

I was finally able to shoot my PS90 at longer distance yesterday (a friend cleared a 200 yard range our on several hundred acres he owns). All I had loaded up was a batch of the 30gr Hornady Vmax’s that Midway was selling back 6+ months ago Powder = True Blue Load = 6.5gr Projectile = 30gr Vmax (fla...

I went out yesterday (with my PS90) and tried some rounds that had a very light dry EEZOX layer and found that romer522 is absolutely correct - poor extraction for those rounds. I didn't put on much, just wiped the rounds on a rag that had some EEZOX on it (and let it dry for 24hrs). It made them mu...

1moreaug - definately let us know what happens. I use EEZOX as well for several rifles and love it... just never considered it for this application. It does dry completely to a film pretty quick so it might work. I was also thinking about some of those polymer auto paint protectors you see in the st...

This is out of the blue but has anyone consider a dry polymer/teflon powder (I have seen it very very fine like talcom) for the cases? I only have a PS90 and the jams I tend to get are always in the magazine just a cartridge past where they start the turn. The cases have most of the lacqure on them ...

I used a 22 hornet FCD to modify - which one did you get? For my application (my final length with attached shim is 1.075") the case goes completly into the die and the shell holder contacts the collet and pushes it (not the shoulder). I don't get any contact on the neck/shoulder area of the case. L...

Keep us posted! For the parent steel the yield and ultimate strength are in the ranges of 40,000 psi and 70,000 psi respectively (welding knocks this down say by 30% if no attention to heat treat etc.). For the FCD I am assuming the clamping load at the crimp is on the order of 100 to 200lb (when co...

In my experience these epoxy materials are typically used to build up parts for remachining (not for joining). I don't think it will work for long if at all if there is no parent material left at the cuts (unless you slide a backing ring up over the die and epoxy the entire thing (the ring would tak...

Well I tried both Lacquer and a much heavier crimp (2/3 of what lee calls max crimp on the modified 22 hornet die that i am using) and both showed much cleaner cases! I was using 40gr Noslers BT's with 5.7gn of True Blue for these loads. I did notice that the heavy crimp tighened up the spread - pro...

how much lacquer do you put on?

I tried it on a few cartridges by using a toothpick to run it around the case/bullet interface - I used an extremely small amount so it might not have much effect (I guess it should wick in between the bullet and case).

Grantness, MO - Thanks, I have been crimping but probably not tight enough. I am using the lee collet crimp (modified 22 hornet) and only have it engaged about 3/8 to 1/2 turn after it touches. Maybe I should kick it up to about 3/4 or so (the directions indicate 1 turn past engagement for max crimp...

I have noticed that the cases are pretty dirty on my reloads from my PS90 and not sure why. The other day I was shooting a bunch of 9mm reload (powder=true blue and unique) and I noticed that with my Springfield XD9 pistol (3”barrel) that the cases were very clean while with my Beretta CX4 storm (16...

Thanks Grantness - I will load up some at 5.7gr with a COL of 1.585" and see how they do.

A friend gave me a box of 40gr Nosler BT's and they look pretty much the same as the Hornady 40gr Vmax. I have reloaded lots of the 40gr Vmax (using True Blue) does anyone have an idea if there needs to be an adjustment in the powder load between the two. My favorite load with the 40gr Vmax is 5.7gr...

The TC sounds great! I assume you will have it scoped so you will be set up to do your own experiment on it.

Apache no problem! I was meaning to comment earlier on your data (especially since I was looking at it when working up these) but the time got away from me. Do you by chance have a measurement of the bearing surface length on the Berger?

Apache – that is some good info you posted. I reviewed your data as a guide with my 30gr vmax’s since when I adjusted your data (for the PS90 barrel length) we get a good velocity trend at the lower loads. I saw you had a big jump in velocity above 6.8gr (which I assumed would be due to a jump in pr...

MO - I totally agree with you and that is why I stopped where I did and probably won't experiment any higher. The 6.5gr range is good enough for my purposes and that gives me at least a 0.3gr safety margin on the high side. I don’t have any Bergers so I can’t compare the length of the bearing surfac...

Grantness - thanks I will use some simple green on my next reloading cycle and see if that helps. At this point I don't thing I will push beyond the 6.8gr load (no need to really go higher since they are pretty fast little things with nearly 500 ft-lbs of energy at the muzzle) - last thing I want to...

I shot some more of the 30 grain reloads today with loads up to 6.4 grains of True Blue. Everything went very well with only one failure to feed (one round wouldn’t turn through the magazine ramp until I bumped it – this is the 3rd reloading on these cases so it’s the lacquer coating). There is a mu...

It looks interesting and might work; however, I question their temperature data (under the technical data tab). 2500F will melt steel and 3500F is into the refractory metal range (they must have slipped a 0 in there by mistake).

I think this stuff might be worth a try!

thanks for the update - I have been looking around for a spray polymer rather then a lacquer but haven't had much luck finding one that doesn't require a hot torch to apply. A polymer base coating would have less senstivity to heat (up into the 200+C range) and be more durable... I wonder what the c...

Thanks - it looks like mine were a little slower then yours. It puzzles me why my cases were as dirty (but they wiped off easy) – maybe it has something to do with the coating being roughed up during sizing (and I did tumble them by accident before reading this form).
