I'm running Lapua small rifle primer. Purchased a bunch of Berger ammo at $1.50 per. Now I've got fire formed brass for less than I could have bought components.
For high volume shooting I am having good luck with hornady. I have about 200 rounds of the bulk hornady large rifle primer and I am currently on my 8th reload and the primer pockets are still tight. For my hunting round I am using ADG.
