The last post has the last batch I fired...03/23/15 post from me

Edited to add chrono type, Temp., Elevation  and distance from muzzle.... 27 Aug.
Edited.........I messed up the data......... arrgh.... So I am re-adding it and separating the 55gr +, 60gr + , and 70gr + , and 54gr -  in their own posts.[/span]

The lists are spread throughout this thread... sorry ...( it is my first rather large posting )


I will list rifle specs first....

16" BCM upper with V7 barrel ,quote.."Manufactured from Rockwell C 30-32 Hardened 416R Stainless Steel. These barrels feature 1:7 improved Polygonal Rifling, V7 Match Chamber, while being V7 Ultra-Match Lapped." ( cut n' paste... easier then me explaining )  Free Floated, BCM Gunfighter MOD 0 Comp, H2 Buffer , FA BCG.

20" PSA 5.56 NATO chamber, 410 SS, CHF, USGI A2 Free floated, FA BCG


2ea 10 shot groups... for a total of 20 rds. per rifle.... Chronograph...Competition Electronics ProChrono Digital Chronograph .... Velocities measured 15 ft from muzzle...Temp. 82-88 degrees... Elev. approx. 232 ft.

[span style='color: blue;']ADDED COMMENTS Sept 20 2014...... YMMV !!!!  These are just observations from shooting so many different ammo types in one day ! So my observations are certainly not etched in stone !

PMC XTAC ( both ) are far more accurate than PMC Bronze.
The fastest 55gr. FMJ's were very inaccurate..... so use that ammo within 100yards if speed is needed.
Most of the older 62gr M855 / SS109 surplus is much more accurate than the current XM855... IMI 62gr M855 was easily the most accurate.
I tried separating IMI Razor by numerically specific Headstamp... No improvement in accuracy.
While accurate enough... Current Fed. "varmint weight" ammo is about 10% slower than advertised.
The infamous thin casehead / soft / loose primer pocket FC AE ammo was really fast.... up to 3144 in 16" and 3316 in 20".... Both Small Letter and Large Letter... Horrible accuracy.
The Fed. "Real Deal" M193 was reasonably fast and accurate compared to the other Bulk Mil-Spec 55gr 5.56
The Hornady 55gr SP ammo wasn't terribly accurate... others beat it easily... GECO 55gr FMJ groups were 1/2 the size.
The Hornady Superformance 55gr GMX was very fast...3130 IN THE 16"....3210 in the 20"... DO NOT USE IN CARBINE LENGTH GAS SYSTEMS !!!!
In my rifles.... the WOLF steel case 55gr FMJ was a joke as far as 100yd accuracy was concerned...worst of all the tested ammo.
While the various XM193 ( White Box, Brown Box, Stripper Clipped,, AE 5.56, ) is allegedly the same .... I will note that there were differences in accuracy and velocity. While that could be attributed to the various production lots.... I certainly saw a difference.
The Ultramax 68gr split every neck, except for the one case that lost the whole neck. This is old ammo , but it still happened. ( LC 05 headstamp )
The Fed. 69gr GMM had the same case head markings as the Fed. 50gr JHP.... hmmm, I thought GMM would use the BEST brass available...
My 75gr handloads were as accurate as 70% of the factory 75gr -77gr ammo... And frankly I didn't put much effort into it. If you handload you can probably easily match 70% of the factory ammo out there.... with better than OEM velocities.
My rifles ( Or me ?! ) shoot the Factory 75gr Horn. better than the Factory 77gr Sierra and Nosler..... while that doesn't make sense... it was easily noticed.
Don't let the low velocities of the SSA / Nosler 64gr BSB's scare you away... that bullet works very well and the accuracy more that made up for it... the SSA was MOA... Nosler 1 1/4 MOA

Next time I will NOT take so many different items ( Lol )... 40 additional types, times 2 rifles, times every 20 minutes the range stops shooting for 5-10 minutes, times writing data, times sorting ammo, times resorting spent brass for visual inspection...etc... = 9 hours at the bench today.... THANK GOD I like shooting !!

Great info, thanks!  Just a quick question.  What distance was the chrony placed from the muzzle of the rifle for these tests?  Were those the actual numbers from the chrony @  whatever distance out it was set up at, or are those numbers that you used a program to "calculate back" the actual muzzle velocity of the rounds given the distance of recorded data from the muzzle?  

Also, what was the temp and elevation?


IMO you should also have a third field out that has the difference in FPS between the 16" and 20".

boy that pmc is weak.. didn't know it was that bad

Agreed ... it shoots like crud out of all my barrel lengths... I wonder if I got a "bad" batch... other people love it.

On the other hand the GECO is great out of my rifles. Very good accuracy for its price point.

I have observed this with PMC in .223 and 9mm. It is discouraging that this appears to be a consistent issue.

?

Great stuff.  Would love to see some Black Hills 69gr SMK in there.

Tyrantresister, I edited my original post with the info you asked.

If my orders show up on time I will have more to add this weekend.

Added 5 75-77gr factory ammo.

Interesting results. Have you tried the ZQI 556 NATO 62g?

Also I have Hornady 55g V-Max, am I safe to assume that these will be as accurate as the Hornady you've shot?

Frankly I would like to see a plastic tipped 69gr as well as a 73-75gr....

Please with sugar on top get this and shoot it through the 16in. I would be mucho grateful as these numbers are nonexsistant

And if you could throw up the yardage at whch it hits 1600 that would be beyond fantactic.

Hmm... I've shot three $10 boxes of 30 rounders and have two boxes left. They shot good (for me) and good groups (at 25 yards) like inside 2". I know my MP15 is more accurate than I am but I was hoping to get your impression of it.

I will do some in the next go around.... as well as some X-TAC, Prvi., SSA, and assorted others...

If I can find some local... I will give it a try.

Thank you sir.

Does anyone know the software to calculate the projected muzzle velocity from those recorded velocities at those distances?

Just a bump for any updates...

since quite a few people here shoot M193 of various mfg's, could you possible test a few more brands?  I know the PMC Bronze didn't perform that well but interested in their XTAC XM193 and the IMI M193 as well.  Thanx much.

I had to go out of town for this weekend.... so updates should happen next weekeknd.

I will be chronographing PPU 55gr , Xtac 55 &62, Independence 55, 69 GMM....as well as a variety of other ammo.

Thanks guys !

Being not so computer savvy..... I messed up my previous data.... and its added info.... crap.

I dont see nuthin...

Sadly.... I am un-spreadsheet smart ... LOL

I am truly sorry about the way it is presented... (  the better, smarter half is out of town for 3 more weeks )

I will see if some of the girls at the office can show me how to input the data on a more friendly spreadsheet.

I would be proud to have the data added for the members here. Give me a little time to get the other data .

If it doesn't have data .... it is hopefully going to be tested this weekend.... weather permitting.... dang rain...

I just added the additional factory ammo that I intend to test followed by all ........................ with no data entered yet.

I was trying to let everyone know what I have on hand to test.

Well stop living your personal life and get on with what a perfect stranger wants. ..geez the nerve of some people.

No the blanks are the ammo I am going to shoot this weekend.

It was just easier to add them to the various tables now.

Zhukov I worked on a spread sheet today... I will try to send it to you , If you have comments or thoughts... tell me .

Remember it is my first spread sheet... Lol... I am a working man by trade... not a desk man. Heck , I taught myself to type.... fast approaching about 40 words per minute... Lol

Thank you for doing this! Looking forward to data on the Nosler Defense ammo.

Updated with quite a few more rounds added... I will add the additional 55gr data tomorrow..... So if it is blank in the FPS... it will be added soon.

I use pmc bronze to tune my carbines. If they will lock back on an empty mag when filthy, unsuppressed, with it, they are good to go. Otherwise I need less spring and or buffer.

Thanks to all the moderators / creators here, for spending their free time helping us with our hobbies !!

After doing these tests I see how time consuming keeping this forum up to speed can be.... Lol

Bfoosh,

thanks man!

I have a 16 inch Bushmaster and 20 inch stainless HB.  

IMI green tip has been the best M855 for velocity and accuracy in both rifles.  Very similar data to yours.

My rifles did not like Hornady NATO super performance 75 grain but did like the std velocity and super performance varmit 75 ammo.    

Both rifles like 53 grain Hornady VMAX.  Am getting 3300 fps out of a 16 inch and nearly 3400 fps from the 20 inch!  (16 inch is over gassed and not recommended by Hornady however).

Try the 53 VMAX if you get a chance.  Fast and accurate.  

62 grain Fusion is going from 2700-2750 fps 16 inch

(temperature sensative to cold) and about 2890 fps from 20 inch.

Interesting that the IMI M855 is loaded to the same velocity as M193.   I wonder how they are able to do that without over pressure?

Also interesting to note how the older rounds were loaded far hotter than they are today.  Federal's old "AE" loading was basically their version of what XM193 is today, except they loaded it even hotter back then?  

Would you be able to test any of the Winchester WB 45 grain HP?  Supposedly a smoking 3,600 fps!  It is supposed to be devastating on game, and there are reports of people dropping deer and hogs with it.

How about the Remington 50 grain jhp?  Thanks.

Blain,

Sorry to say they did not live up to their claims... ( still have to post the rest of the info... )

Win. 45gr JHP 16" 3049 Av. .... 20" 3180 Av. .... Mediocre accuracy.

Rem. 50gr JHP 16" 3034 Av. .... 20" 3200 Av. .... 8 shoots in one hole... 2 fliers

I also have data for 7 other tested loads I just need to find time tonight to post.... I will say that the Winc. 5.56 64gr BSB and 77gr loads are fast.

Also 3 other loads waiting on the well known slow delivery guys.... Lol

I hope to also add .308 / 7.62x51 from a M1A... just need some decent weather and more time.

Is that Wolf .223 steel or brass (Gold)?

Sorry,,, thanks for pointing that out.

My 55gr Wolf shown is the PolyCoated steel cased.

I am waiting on better ( sunny ) weather to test a bunch more... including the Wolf Gold 55gr FMJ, BH Mk262, Rem. , Fiocchi, Fed. GMM 77gr and Fed. 80gr ( Long throated barrels only ) as well as a bunch of other gathered .223 / 5.56.

After the sun cooperates ( for the chrono ) I will be adding 22" ( M1A ) .308 / 7.62x51 ammo.

The dismal performance  of the PPU 75 grain match is disappointing.

Yeah, I have had dismal accuracy results with PPU also... but you won't know unless you try.

I never would have guessed Fed. AE 50gr Tipped Varmint would be as accurate as it is... and cheap.
The same can be said about GECO 55gr FMJ.
