Are you a shooter that hunts, or a hunter that shoots? I am more the former, and find myself always fiddling with loads, trying to tweak them, but in actual, practical use, any large game rifle that will stay under 3 moa is sufficient. If I were going to hunt "big game" in the entire lower 48 today, practically any off the rack rifle in 7mm to 358 would be just fine. My 9 year old grandson in his 1st season this year took 2 does on the 1st and 2nd days, with a 357 mag that was getting 1 3/4" groups at 75 yds. On the second one he head shot it, because he saw how much mess there was inside the 1st one. One hole groups are great for the ego, but for the find it, shoot it , eat it school of hunting, minute of Moose is sufficient.
