Another thing about the 300 rum is that for whatever reason everyone I have laid hands on has been a shooter and a very easy round to work with. Retumbo, and a GMM215 work well with any bullet from 150-200.
I think that GMM215 is the way to go with that caliber, also. Mine does great with 200 gr NPs, but not so good(thus far) with the AB. I will keep trying, as I really like the looks of as well as what I hear about that projectile in the .308" 200gr.
