Parabellum Research PBR 200 FMJ pull-down

[The_Shadow]

Yes I will CHRONO after the pull downs and documentations are made then reassemble them back to the original measurements as noted prior.  Then I'll test them and trying my best to recover all the brass fro further details. 
The bullet did weigh 200 grains on the PBR.
I had thought abouth the WC820 as a possibility for the powder, but I list it as AA#9 for less confusion.
Each cartridge to be tested has it's own word document simular to how you see in the post with the pictures.
This week we have friends and family dropping in so that may occupy some of my time as well.
Please be patient, as I don't want to rush the process, the results will be more accurate that way.
I am as interested to know as all of you...Thanks for your understanding.

Shadow, I'm curious how you positively identified that powder as AA9? Are you just going by the charge weight and appearance, or something more?

I did compare to my supply of AA#9 which is slighty darker, also as mentioned earlier the data actually fits very close to older Acurate Arms data for the 200FMJ showing 13.5 grains @ 1200 fps.

Thanks. Just wondering if it was a pretty solid guess, or actually a positive ID. I don't disagree with you that it appears to be AA9, but I wouldn't call that positive ID.

True it is harder to say absolutely positively I suppose for this one as compared to mine , I have read that recent Acurate Arms powders have gone thru some changes like more sperical to a more flatten ball consistancy.
BTW I did compare this one to my Winchester 296 and Hodgdon H-110 because they would be closer to fit the profile but the pressures would be higher than with AA#9 from other data I looked over.
I don't think it is 2400 either, but I don't have any left to compare with, if I recall it was smaller flakes inbetween Power Pistol and Blue Dot, but closer in profile weights as well.
I welcome anyone to post pictures to compare with these to help make a more absolute ID.

In this thread http://10mm-firearms.com/factory-10mm-ammo/ted-nugent-ammo180-jhp/ I just posted picks of No. 7 which looks exactly identical to my No. 9 powder, even under a magnifying lens (I just checked ).

[sqlbullet]

Yeah...but 14.0 grains of #7 would be way over pressure profile I am pretty sure.

I agree that it is probably AA9, based on the charge weight and appearance. With Accurate powders though, you really can't identify them by appearance. There are several other powders that look similar, including AA7 and A1680 in Accurate's lineup, and Ramshot powders. Maybe some VV powders too?

[The_Shadow]

Youndering if you have some of those powders could you post pictures?  It maybe useful for my studies because I haven't worked with the VV or RamShot powders yet...and not much info about loading 10's to that level or profile 
Thanks,

Just a thought, but due to cost I'd be surprised to see VV powders used in commercial loads in the US.
As always, I reserve the right to be wrong.

[Yondering]

Sorry, at the moment I don't have any VV or Ramshot pistol powders, only rifle. I need to spend a few hundred bucks to restock my powder selection again.

[The_Shadow]

The more I study this powder I don't think it is AA#9, I will go back an place a question mark on this one...why I just looked over another load which is AA#9 and did a better comparison and they are very sperical round and dark, almost black in color.

The power in the picture is more of a flattened ball type and not as dark and spherical like AA#9

100% true.  It's just that since it looks identical to my No.9 powder I saw no reason to take more pics, therefore suggesting to use my No.7 pics as a reference to No.9 also.

I wouldn't think it's a VV powder either.  Seems to me you can't even fit 14.0 grains of a VV powder that even has a chance of working in this application into the case under the bullet at 1.260" or less.

The more I study this powder I don't think it is AA#9,

I don't either.  It doesn't look like my No.9 which looks exactly like my No.7.

The only other powder I think it might be is Ramshot Enforcer which I have been told is very similar to what No.9 does.  It sure as heck isn't True Blue or Silhouette, and beyond those two and Enforcer leaves us with Ramshot rifle powders that wouldn't fit the scenario either.

Ramshot Enforcer is definitely my best guess.  Plus I've heard it meters super sweetly, and from what I see in your pic it appears that powder would meter super sweetly.

My second guess, which is a WAG, would be Accurate 4100.  But I don't know what it looks like, or what it's capable of.
