I am going to have a new rifle built and am really struggeling on 300 win mag to 338 edge. Somewhere in there is where I want to land but not sure. Will definetly have a muzzle break and be around 9 lb. rifle before scope. I want to enjoy shooting it without taking a beating. I have a .30-06 and 7mm mag so I want something larger pretty much for elk, long range shots, sub 1/2 moa, and just fun. What caliber is a good balance of recoil and velocity within the caliber range above? Thanks for the help.
