not sure what caliber your thinking about. but 224 bullets dont work in 300 blackout. yes its in an ar platform and cut down 223 case but uses a 30 caliber bullet and pistol powders. i load from 110 grain up to 240 grain subsonics for my 300 blackout. doing load development for light weight subsonics now.
