[QUOTE="Paladin300, post: 2788108, member: 115299"] How much free bore are you running and what twist? I am running .25 fb with a 1/7-1/8 twist in a 27” barrel. Nosler brass 210M primers and R23. 58.5 gr, in a Krieger barrel. I would start with a lower charge and work up. I have a friend who runs 42.5 grains of H4350 in a Creedmoor with no issues. I blow primers at 41.5. Every rifle is different. Have fun and be safe. Chamber tolerances, barrel throat and free bore all make a difference. You should be able to get to 2800 + with a standard 280 AI. [/QUOTE]
