223 rounds for my AR. I need to use Hornady 150gr BTSP bullets, but can’t come across any info to support that. Experience tells me the 550 press prefers a ball type powder. Any notion wherever to begin? The aac-sd with 110gr Sierra varmint bullets will shoot a clover leaf https://johnathantdnxi.blogofoto.com/68925829/brass-300-blackout-secrets
