I have a buddy that got a new build 300 Win Mag from someplace here in Texas.......Alamo maybe? Anyway he does not reload and has asked me to help. The gun has a Bartlein (maybe 2 or 2B) and Defiance Deviant Hunter action so no reason it shouldn't shoot. The whole thing is very light so I'm sure I'll have a blast shooting it At any rate, he has purchased and given me 100 pieces of Norma brass and a Redding Type S full size match die set. I don't have a 300 Win Mag but I do have several 215 Hybrids, some 215Ms and a lot of H1000. Any ideas on where to start and if these components will work would be much appreciated.
