I use CCI450 and BR-4..I have used CCI400s before with no ill effects but they do have a thinner cup and are noticeably more flattened than the 450s after firing. All of my .223 loading is for the AR style rifle FWIW
Well, Robert Hutton liked it......The only one I was unsatisfied with was 4198. Metered terrible, gave low velocity and mediocre accuracy in my experience. Others seem to like it, but maybe they have never chronographed their loads or have lower accuracy expectations.
OP, as you go looking for small rifle primers for 223, avoid Remington 6 1/2 Small Rifle primers. They will NOT work in 223. They are meant for low pressure rifle rounds, specifically 22 Hornet.
They even have a warning printed on the side of the flat/box :
.22 Hornet. Hot .38 Super. Likely other pistol applications where a mag primer is called for.I have several thousand Rem. 6 1/2's that I brought in 1994 that I want to shoot up.
I have about 400 left from 1000 I bought before I knew they were practically useless. I have no idea why Remington is still producing a primer that is only recommend for use in the 22 Hornet. I have been using them up in .357 Magnum ammo. OP, Do Not use them in .223 ammo.I have several thousand Rem. 6 1/2's that I brought in 1994 that I want to shoot up. I already have loaded 60 rounds of .223 brass with them.
