Since you don't have the Lapua bolt face I would recommend what I did, build a 30/28 nosler and use ADG brass. After fire forming I was looking at an h2o capacity of 103.3. That's pretty darn close to a 300 Norma yet you don't have to have the Lapua bolt face! I run the 215 hybrid at 3010fps out of a 26" barrel (Proof CB). I could run it faster but I'm in a great node at that speed right around 59000psi. You will need CIP length magazine and FB 215- 225. If you don't want to go to all that trouble then 30 nosler using ADG brass. You will gain capacity of the nosler brass and the ADG brass is outstanding!It's the standard mag face, but I have the couple pc from Weatherby that you need to open it up for the larger face for the lapua/378 sizes
Yes I wanted to run a 1:9 so if I wanted to push the heavyweights I could, and after taking to Hart that's what they suggested as well. I have also looked at some mono bullets that would need the faster twist then the 1:10. Figured would rather be a lil faster twist then be too slow
