Your probably right. Every time I tryed measuring it I got a little different answer.
Your recommendation about autocomp, have you had any troubles with hs6?
HS6 is excellent in the PS90 too, and has an excellent case fill percentage - my SD numbers were just a little bit higher than w/ AutoComp.

HS6, AutoComp and Longshot are among powders that I trust to get at least 2300 fps with a 40gr Vmax without some type of problem...

AA#7 and True Blue can get 2300+ for instance, but up over 2300 and I have seen mag pops and jams, etc...

Overall, HS7 is STILL the best I know of thats in this country. Im gonna keep working on my contact at Alliant and see if maybe just maybe they could fill that gap left by HS7's removal from the market. Every load in every manual I say always beat out HS6. Autocomp is better than HS6 for sure.

I havent tried HS7 in the PS90 - the problem is that the PS90 is soo picky - so I'm not sure if it will like it or not...

Here are some pics:

Just picked up a case prep assisstant...

Close up -

Comparison of various .224 bullets I have used in the 5.7

Hornady NTX loaded round -

The 35 NTX has nearly the same Ogive as the 40 Vmax - A die set for an OAL of 1.575" with a 40gr Vmax seated the 35 NTX at 1.584" - so Ogive is fairly close...

Those case prep machines look nice, but they are SO expensive. That's why I went w/ the Trimpro, EA Trim Plate, and the cutting head w/ built in chamfer/deburrer (one step and ure done). Rigged an electric drill to run the trimmer. Although...since I didn't exactly know what I was doing at the time, I prob spent almost as much on my sliding electric drill rig as the RCBS electric trimming attachment :laugh:

I got the case prep for a really good price - I have a dealer who treats me well :D

I wanted the case prep because i get sick of charging the battery on my drill (I was just chucking in my attachments). It seems I am always running batches so hopefully it turns out to be a good tool to have!

Plus, I use an X Die for the 5.56 cases so I dont need to trim, just chamfer... So this should be a good choice I hope!

VeTTeMaNC486 -

HS6 seems to be an excellent powder to light the 35gr NTX in the PS90 - It did better than Longshot and AutoComp from a potential Kinetic Energy Standpoint in my initial tests. Of course there are other things to look for like reliability in all temperatures, consistently low SD's and Accuracy...

HS6 also pushed the 35gr NTX out of the FsN better than AutoComp and Longshot too.

Overall I like the bullet so far. You cant reach the same KE potential of the 40gr Vmax, but it does come pretty close. The 35 does shoot a little faster and would give a very flat trajectory, so that is a bonus to be considered.

Alright, back to the load bench for another test run :thumb:

Awesome. :thumb:

I was hoping you would be able to get them coming out a little faster. Seems like the 40gr vmax is pretty tough to beat. Soon, I plan on loading up some high power loads with them and hs6 and testing them for accuracy and reliability. I like how the numbers look with hs6 under the vmax.

I am going to go to the range in the morning to sight in my .45-70, when I get back I will try to load up some nosler 40gr over some blue dot (and possibly Accurate #7, depends if I have enough time) and try to shoot them over the chrono before school tomorrow evening. :D

Looks like were going to have to wait on the 40gr nosler lf results, had a self induced chronograph error. I believe that is the politically correct term for it. Crap. Oh well, this one lasted WAYYYYY longer than the last. One conclusion can be made; whitebox ss195 has NOTHING on the damage that a 40gr nosler does to a hard target. :(

I am going to start hanging a target up behind the chrony. That should help.

I did shoot all the way up to 6.8grs of blue dot behind the nosler and had no problems, however I am going to remove my lead tape, the action feels funny cycling with it. I will just wait for EA's bolt weight I guess before I mess with max power loads much.

How are you suppose to help with data when you have 'self induced chronograph errors?' :p


Some more of my data - I will put in in my load threads later too...

PS90 - 35 gr. NTX

Dillon Progressive w/ AutoComp @ approx ~ 5.65grs | N=10 | CCI 400 | SS195 Brass

Avg - 2400 fps
SD - 9 fps

Dillon Progressive w/ HS6 @ ~ 6.55grs | N=10 | CCI 400 | SS195 Brass

Avg - 2429
SD - 21 fps


AutoComp has proven itself time and time again as being the most consistent powder in the PS90 with very low SD's.

HS6 works really well, and can achieve some of the highest speeds without mag pop ups or jams... However, recoil is 'stronger' than with most loads, likely due to the burn rate and corresponding speed/recoil associated with this powder type...
----

FsN - 35 gr. NTX

HS6 | N=6 | CCI 400 | SS195 Brass

Avg - 2033
SD - 20 fps

Good function...

This is the second one this ps90 has caused to malfunction. I will get a replacement when I get back from vaction next week. From now on I will be putting a target or something up behind it lol.

remember, you don't need to touch the sensor with the bullet. Ya know those sky screens? I bet it sees the bullets way up there :p :lmao:

:facepalm:

I'll post a pic next week when I get back from vacation. Made a huge mess of it. I'm thinking about upgrading to a better one, but at the rate im going I may as well invest in multiple cheapys :laugh:

Remember the reactions by so many people when I stated the Chrono gets it all the time and we shoot ours fairly regularly. Everyone, most with out a chrono, stated how hard it would be to hit it and how could I who shoots so much hit one.


Well now you know how easy it is don't you?

I put the dot of my delta point on my PS90 about a half inch under the skyscreens - that puts the bullet about dead center. Ive never shot a chrony :p

This is the second chrono that this rifle has claimed :laugh:

Aiming at the skyscreens with the ps90 is a pretty excellent idea.

I just have my wife stand on the opposite side and ensure the muzzle is properly aligned for the shot, then she ducks.

Just kidding. :D
