Curious if you are using a weight on the bolt of your ps90???
I am thinking about removing the lead tape on the bolt of mine and seeing if my load will shoot without popping the mag.

iFire · Post by **iFire** » 16 Dec 2010, 16:58

No, I am not using a weight. These loads are with my stock ps90.

I am going to make a new ROF stabiler with added weight soon. Then I can test the difference a weighted bolt makes...

Interestingly enough, the mag on my gun just never seems to pop up. Not even with loads that I have have put through the gun that are downright crazily overcharged. I have had it pop only once in all my shooting... who knows...

VeTTeMaNC486 · Post by **VeTTeMaNC486** » 17 Dec 2010, 11:11

The weighted bolt should help with the empty cases getting stuck between the bolt and the barrel. If your mag isn't popping or the cases on non over max charges are not getting stuck in the action I do not see how you would have anything to gain. EA is supposed to be testing one, I will purchase one when it becomes avalible. For now I have lead tape, I believe 35 grams worth.

There is a good thread by ninthinning in the ps90 section about weighting the bolt, if you are interested do a search for high power bolt mod (I think that is the name of the thread).

iFire · Post by **iFire** » 18 Dec 2010, 10:26

Some A#9 and AutoComp data added...

Quick note:

1)The "new" A#7 formula will not get you the same velocity as the old formula - expect less velocity at any given charge - The max loads i listed are ok to use because the new fromula is slightly "weaker"... The new formula might have a higher max charge because of this, but it still wont get you up to the same velocity. It just doesnt work as well as the old formula...

If your unsure of which one you have, this is how mine are distinguished:

Old
1) Lot number is a sticker on the bottom of bottle (No silver bar on back of label)
2) DOES NOT have "Made in USA" on side of bottle in red

New
1) Lot number is on the back (right top) of the label in a silver bar
2) On the side of the bottle under Western Powders it says "Made in USA" in red

VeTTeMaNC486 · Post by **VeTTeMaNC486** » 21 Dec 2010, 09:27

Epic thread man. Since apparently there are two different blends or w.e of accurate #7 you should make a distinction asw to old or new formula on the load data for it.

The weight in the above link is a new addition, it is not being used for the data in this post.

As i mentioned before, I have had the mag pop up only once in all my shooting, so I know what your talking about, just doesnt happen with my gun except for that once...

ninthinning · Post by **ninthinning** » 03 Jan 2011, 05:40

Thank you for posting photos of your PS90. When firing powerful rounds with my PS90 the magazine did not pop out on each shot. When there was just one round in the magazine for test shots the magazine did not pop. This may have been because the gases flowed into the empty magazine space and reduced the gas pressure. Also, when shooting multiple high power rounds, the magazine would pop two out of five times. In your tests did you use single rounds for the high power rounds or did you load multiple rounds?
Thank you,
9th

iFire · Post by **iFire** » 03 Jan 2011, 07:43

Ok, let's say I build a ladder of rounds - 3 each of 5 different charge weights - then I would have 15 rounds in the mag for that particular test...

I have loaded as many as 25 or so for testing and as little as maybe 3 or 4.

As would be expected, as I shoot the strings of shots, it is continually moving closer to empty.

The only thing I could think to do differently, if it would even matter, is to load some dummy rounds on the press and use them as fillers so that my mag is "nearly full" during the test strings and see what (if any?) difference it makes. Dummy rounds would just be smart so that nothing gets mixed up...

When I was playing with 55gr fmjs and Blue Dot my mag was popping up and I was only loading 5 in it. Sometimes it would pop on the last shot too (I believe). I did not find any correlation between velocity reading and the mag popping.

Good to know. I might not spend much time testing the difference the number of rounds in the mag makes then...

see this post, it has some ideas of mine about the mag popping up...

I've had some of my lowest Standard Deviations with AutoComp in the 5.0-5.2 gr. Range in the PS90 - That would be a good load to try our for accuracy I believe with the 40 gr Vmax...

There are several other loads you could try as well using powders like longshot, hs6, etc... It just depends how much testing you would want to do...

Hello iFire I just have a quick possibly stupid question for you. All your data is great by the way cause you can't find anything like it anywhere. But my question is are you using small pistol or small rifle primers in your load data, I have heard of people using both. I may have missed it but just wanted to clarify. Thanks for the info!

When I called them they said they switched manufactures and that it was the "same" - of course as soon as i did a side by side comparison I found out that wasnt true - Velocity is around 100 fps less with an equal load of the new powder...

The new powder 'may' have a higher max than the old powder though and thus be able to achieve the same velocities, but I havent tested it thoroughly enough yet to know for sure...

Do you know when they changed manufacturers?

Not sure exactly what date they changed it... Below is the info I posted earlier about the change and how to tell the difference

Quick note:

1)The "new" A#7 formula will not get you the same velocity as the old formula - expect less velocity at any given charge - The max loads i listed are ok to use because the new fromula is slightly "weaker"... The new formula might have a higher max charge because of this, but it still wont get you up to the same velocity. It just doesnt work as well as the old formula...

If your unsure of which one you have, this is how mine are distinguished:

Old
1) Lot number is a sticker on the bottom of bottle (No silver bar on back of label)
2) DOES NOT have "Made in USA" on side of bottle in red

New
1) Lot number is on the back (right top) of the label in a silver bar
2) On the side of the bottle under Western Powders it says "Made in USA" in red

Added some 35gr Nosler Lead Free data.

Also added a bunch more shots to the sample size of various loads. My load notebook has SO many strings of shots that I still dont have included in the data. Its just takes so much time to go through and re-read it all :laugh:

Loaded 30 rounds with 40 gr VMAX with 5 grains of Alliant Steel - shot 15 rounds this afternoon from PS-90 at 75 yds. All 15 rounds cycled properly. Primers and casings looked good. Sorry no chronometer data.

Thanks for the load data.

Your welcome - Glad to see that Steel worked well for you - @ 5.0grs with a 40gr vmax its very consistent and safe!

I have some data somewhere with hs6 and 55gr fmj up to 6.0 grains, was only sample size of one though. It functioned fine and I believe it was around 1900fps, but I would have to find my notes to verrify this. I wonder how the trajectory would compair with ss197?

Seems like the new accurate #7 leaves a lot to be desired compared to the old

Posting from my droid so I reserve the right to have terrible grammer :p

has anyone got load data on universal powder? maybe clays?

For what bullet/use? I've used clays in a subsonic test but it wasn't worth pursuing.

Have you tried the search function? I don't think they are mentioned in the Forum Wiki but couldn't swear to it.

40 gr nosler ct in a ps90

Post by **Rapier1772** » 30 Jul 2011, 18:23

Since it is for a PS90, I moved your posts over to this thread. Trying to keep it as straight as possible :thumb:

I do not think Clay's is a good powder for this round. At 2.7gr it was filling the case & the speeds weren't anything impressive & accuracy kind of sucked.

A quick search for universal powder came up with this: viewtopic.php?f=19&t=10903" onclick="window.open(this.href);return false;

The don't even list accurate 5 which is great in the ps90 fard to find where i live

Western Powders listed their own loads for Acc#5, but everything for #7 is far superior.

Grant what about titegroup any experience? I have 2 stores to get powder from and don't want to order it on line really both carry alot of hogdons and thats about it so am limited at what i can get I might just need to go north and get true blue or 7 next packers game lol

Post by **Grantness** » 31 Jul 2011, 13:13

I don't have any experience with titegroup. The burn rate looks too fast for optimum performance.

(I realize it has been almost a year since iFire has visited the forum, but I figured I would throw this question out for anyone to answer).

Excellent work iFire. I was reviewing your 40g V-Max True Blue data, and I noticed something. Your starting load is 5.6g TB, and after that you started having hit or miss function problems. But, in their current load manual (http://www.ramshot.com/wp-content/uploa ... _rifle.pdf" onclick="window.open(this.href);return false;), Ramshot lists 5.6g TB as the MAXIMUM load. Granted, their data was developed with the FiveseveN rather than the PS90, but I was wondering if that may be the reason for the hit or miss functioning.

grimmond · Post by **grimmond** » 09 Jun 2013, 12:38

I do not have a PS90 but I believe you might be on to something. Crunching the numbers from the Ramshot page to figure the velocities at the 18% increase they say for a 10" barrel would put the velocity approximately at 2183fps out of a 10" barrel. His velocity is a little higher which is caused by using CCI 400 primers, which I personally found to be a little hotter then both of the primers listed in that article. Also if you look at the pressure listed at max load it is approx 48,800 psi. If that pressure is accurate his loads may be pushing close to the maximum pressure which could be causing his inconsistencies and magazine pops. Also True Blue may not be the optimum powder for the PS90 platform. I believe that I read it somewhere that slower burning powders are better, because they peak later in pressure. But one of the long time guru's here will have to weight in on that. Also he didn't list whether his barrel is the 16.5" or the 10" and whether he has EA's HD mods done to his PS90 which might change the parameters of the results.

Has anyone tried the 35gr NTX with True Blue? Ifire posted some data on that bullet with other powders, but True Blue is what I have. The bullet is longer than the 40gr Vmax, so with the same OAL I will get more pressure.

roostercogburn · Post by **roostercogburn** » 04 Sep 2016, 06:05

I think I have pretty descent FPS with 36g Barnes Varmint Grenades and 5.5 grains of AutoComp. Last batch was 2320 out of a 16 inch barreled bolt action. Does that seem on par with what others are getting from that barrel length or should I be getting faster?

1x fired FN Brass
CCI 400 small rifle primers

Post by **panzermk2** » 06 Sep 2016, 12:11

Yep with 1x brass it is.

The 35gr VG has a long shank for weight, meaning more bullet in contact with rifling, so you can't push it as fast as a same wight or even slightly heavier bullet with less shank.

fantastic, guess it is time to start playing with other bullets then. I wanted some 55g sub sonic loads as well so will start trying those out. I see the data for the 40g VMAX up around the 2500FPS range, you think that is about the limit for that round as well?

I looked on your web page for brass but could not see anything. Do I have to be invited to see your page? I have a few thousand of this once fired brass I got for free so no gonna complain right now. It is kinda finicky though, those FN guns do a number on brass. Would love to get my hands on some virgin brass just for the bolt gun, it is way less damaging and I feel I could get more reloads out of it on a conservative load.

How does the difference in case capacity affect pressure?

Post by **panzermk2** » 19 Sep 2016, 10:22

The case is a combustion chamber. Smaller chamber means higher pressures with the same amount of powder when compared to a larger chamber.
