Re: Primers recommendations for 300 Win Mag
My testing to date:
Berger 190, RE 22 (74.0gr), Win Mag Primers - 3072 fps
Berger 210, RE 22 (71.2gr), Win Mag Primers - 2918 fps
Hornady 180 SST, RE 22 (75.6gr), Win Mag Primer - 3118 fps
Hornady 180 SST, RE 22(75.6gr), Win Lg Rifle Primer - 3128 fps
Hornady 180 SST, IMR4350 (70.0gr), Win Mag Primer - 3033 fps
I made an error on my Lg Rifle vs Mag primers. It was only a 10 fps bump with the Lg Rifle powder....should have know better than trust my memory.
