I started out loading/shooting an AR in the 204 but got tired of loosing prepped brass so traded it for an over/under shotgun and a Savage 110 in 7mm Mag. I recently ordered a 204 barrel from Northlander and will be converting my 223 Rem so all I have to do is change the barrel. Any good starting loads for a bolt action with Nosler 40 gr BTs, Berger 30 gr FBHPs and 39 gr SBKs?
