Re: Ultrasonic Solution??

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...

Re: Case width issue with Lee dies

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 ...

Re: Case width issue with Lee dies

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...

Re: Gun Safes

I agree with you guys regarding the claims by these companies and whether you can trust there claims.

Re: Gun Safes

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...

Re: Gun Safes

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...

Re: Military Sniper Rifle

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...

Re: PS90 HD Bolt Rate Reducers.

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!

Re: PS 90 Accuracy

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...

Re: PS90 Owners I Need Your HELP!

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...

Re: PS90 Owners I Need Your HELP!

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...

Re: PS90 Owners I Need Your HELP!

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 ...

Re: Crimping the 5.7x28mm

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!

Re: Crimping the 5.7x28mm

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...

Re: PS90 Owners I Need Your HELP!

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...

Re: PS90 Owners I Need Your HELP!

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...
