I use rcbs 5.56 small base dies, I been shooting heavies out of mine. But did work a load up using 55gr hornady fun. Natchez has them on sale right now 7.99 a 100. I was going to order some until they wanted to charge $62 bucks to ship them to Alaska. I only used tac with a 75gr load. I use cfe223 with my 55gr load. Far as primers, I use either Remington 7 1/2 or WSR.. but can’t go wrong with cci450 i have messed with cci400 as well, with no issues.
