Ima gunna walk on the thread .. ooops
I use Small Rifle Primers in my .45ACP sm primer cases. CCI#400s to be specific. Worked the load from the bottom and ended up with my usual powder charge without any noticeable difference from my regular LPP .45ACP load.
3.8g Clays
CCI#400
230g Bear Creek Moly RN / 230g Xtreme RN
COAL 1.22"
OH! and never use SPP in an AR platform. Bad things can hapen like the potential and likely, slam fire
