223 rounds for my AR. I need to use Hornady 150gr BTSP bullets, but can’t find any details to assist that. Expertise tells me the 550 push prefers a ball sort powder. Any idea wherever to get started on? The aac-sd with 110gr Sierra varmint bullets will shoot a clover https://300aacreloading18416.blog5star.com/38246639/300-blackout-reloading-can-be-fun-for-anyone
