What the hell happened to PMC!!!

[GunnutAF]

Let me first apologize to those that have posted recently about how weak PMC Bronze ammo is! Your right! I bought a case just before the crazy hit - the LGS had a couple cases and the price was good!
I hadn't chronied any Bronze for a couple of years ! Last time I got 3025 fps out of a 16" carbine! Didn't write down that lot# sorry. The Current Lot # is 223A-0546 on the batch I shot today. The following chrony data was from a Savage Hunter 11 22" barrel chrony at 10'!

Avg 2814 fps
SD 19.6 fps
ES 31 fps

1.2809
2.2806
3.2797
4.2875
5.2794
6.2782
7.2837
8.2813

I chronographed 100 rounds of PMC Bronze last year out of my 16 inch Noveske...got 2886 FPS with an SD of 46.

They must have read about the airline that saved money by taking one olive out of the salad they served. 1 grain of powder out of how many rounds equals a shit ton of savings?
Just a theory.

It's designed to run in overgassed guns - the usual suspects - Shrubmaster, Delton, RRA, DPMS, CMMG, et.al. - all the rifles no self-respecting M4C regular would ever own.

For inside 100, its great ammo.

I posted what I saw running a Noveske 16" and 10.5" on ARFcom and was practically lynched. It was very low powered and some were so low powered that accuracy was all over the place. I spent twice as much ammo as normal. @ 160 yards some would drop way out in front of my target. I sold it all and stopped a Cabelas order before it arrived. Glad to see from here and the other forums I have been vindicated from my findings!! I will say they (PMC) should have spent more time with loading spec than ascetics because the ammo was very pretty.

I have never had good luck with PMC ammunition. It has not been accurate out of 3 carbines and 2 match rifles. It's the slowest factory 55g ammunition I have fired and below the accuracy node for my rifles. I use it for practice and matches inside 100 yards.

Here are some average muzzle velocities out of my duty carbine with 16" barrel for reference:

PMC 55g FMJ (red & white box) - 2673 fps
Black Hills 55g FMJ - 2726 fps
Win. Q3131A 55g FMJ - 2964 fps
S&B 55g FMJ - 3041 fps
Win. USA223R1 55g FMJ - 2888 fps
S&B 55g FMJ - 3041 fps
Malaysian M193 - 3065 fps
Rem. 55g FMJ (green & white box) - 2904 fps
Federal M193 - 3059 fps
Federal 55g SP - 2953 fps
Win. 55g SP - 2949 fps

All velocities were measured at 15 feet from the muzzle at a temperature of 55 degrees farenheit. The S&B 55g FMJ, Malaysian M193 and Federal M193 all measured between 3240 fps and 3260 fps out of my match rifle with 20" stainless barrel.

While bronze is very slow it is not as bad as you are claiming. It is not so slow that it is going to drop into the dirt at 160 yards. If it was dropping in front of the target it was the way you were aiming. If you look at the posted differences in velocity that is not enough to go from on target to dropping in the dirt on the next shot. The only explanation would be that you were shooting in the dirt. Even if your target was 8 inches above the ground. The bullet is not dropping that much.

Op you might be having some chrony problems. Either weather or setup. The only other thing i could see is a mix up of bronze and xtac. Your velocity of 3025 from a 16" barrel is very fast. Bronze seems to range from 2650-2750 for a 16.

Well it did - i kept some for some cqb shoot house - but it sucks.....

Is it not properly functioning in your AR? As much as people complain about it being under powered, I've never had a problem with it functioning & cycling correctly. It runs fine in all my ARs (6920x2, LMT MRP, DD LW Middy, Colt Sporter) including a brand new DD MK18 SBR during Pat Rogers COC. The accuracy wasn't that bad at all but I've never shot it past 100 yards. It's acceptable for my needs (training), but so is Wolf & Brown Bear, so I drive on with it.
