.223 sellier & bellot or .223 pmc bronze

[JoeBobJoe]

I have heard PMC ammo is much lower velocity than other manufacturers of .223/5.56
I'm thinking of going with Sellier & Bellot .223 over the PMC bronze .223, any info on this that may sway me away from S&B to another brand or to go with the PMC bronze would be appreciated.
I'm using ammo for range use it's .223 55 grain fmj. I usually run IMI 5.56 55 grain.
Thanks again for any input.

PMC Bronze 55 Grain FMJ


I evaluated the accuracy (technically, the precision) of the PMC Bronze 55 grain FMJ ammunition using my 20” stainless-steel Lothar-Walther barreled AR-15. This barrel has a 223 Wylde chamber with a 1:8” twist.

Three 10-shot groups fired in a row from the bench at a distance of 100 yards had the following extreme spreads:

2.22”
1.82”
2.15”

for a 10-shot average extreme spread of 2.06”. The 30-shot composite group had a mean radius of 0.72”.

Unfortunately, my cocker spaniel chewed-up my chronograph data for this load.


The smallest 10-shot group . . .

I also wanted to thank you for the information. I had a long held impression from the web that it was more accurate, but slower than most of the 55gr FMJ.

I never fired much of it because when it was inexpensive, so was 5.56 spec ball.
