Small pistol primers in 223 loads?
I have a few thousand small pistol primers CCI500. I have CCI450s as well but try to save those for my precision 6GT loads. I never load 9mm pistol - only 45 so I decided to use a bunch.
I loaded up the following 5.56 load and tested:
Berrys 55gr .224 FMJ
26.0 gr XTerminator
LC Brass
CCI450 & CCI500
COAL 2.24”
Rifle used was a Colt 6920
No pressure signs. No appreciable difference with velocity, SDs, or accuracy. No slam fires.
I even loaded randomly and couldn’t tell any difference when shooting.
For me I’m going to keep doing it. But I’d love to know what the differences are in primers between SRP SPP and SRPM or if I’m missing something about why I shouldn’t do this.
