I am going to build a new hunting- longrange fun rifle. I'm building a 7lb rifle plus optics. Thinking a Surgeon sa, a Proof Research barrel 20-22". I'm asking for some advice on what round would do the best with this size barrel. What expected velocities would I get. With the 6.5 Creed and Lapua shooting 140 Berger Elite and the 308 178 ELDX bullets.
