Just starting to reload and I need to buy a die set. I’ve got a Rock Chucker single stage press. I’m going to be reloading 6.5 Creedmoor for hunting. I’m not shooting BR but I want really accurate rounds. Sounds like some die are more accurate for the seating depth? Do I need a 2 piece or 3 piece? Can I use any brand on the RCBS press (like Forster)?
