Lapua, adg, Peterson, alpha, nolser. I haven't used alpha or Peterson yet. I do have some Peterson 6.5 creedmoor brass in the reloading room. My adg 7mag brass primer pockets have been tough as hell, and the load is shooting so good I didn't think I could shoot that good at 600 yards. Lol so I try to stay with lapua and adg.
