That sporter weight barrel is not designed to shoot one holers. Also with as much powder as you are lighting up in that thin barrel it will heat up quick and stay that way for a while as it does not have the heat dissipation rate as a larger diameter barrel will have. You are shooting under MOA with your reloads and that is darn fine for a hunting rifle. You didn't say what kind of groups you get consistently with the factory ammo but if it does 1.5 MOA to 2.0 MOA then it's doing what it is supposed to do. You may want to check headspace and the muzzle crown as well just to be sure that nothing there is out of whack. What twist rate is your barrel and what grain of bullet are you shooting?
