I've seen where everyone says not to use them in 223 because of the pressure difference of the 22 hornet that its intended for . But what about 300 aac blackout?
In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington, 204 Ruger or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.
But Remington also has SPP so what good?They work great in .38SPL loads.
