If I had to chose one rifle to do all my hunting, elk to groundhogs, it would be a 7 mag. I've had two, and maybe I was lucky, but they both consistently shot under .5 moa. I had a brake on one, and with that rifle was able to comfortably shoot 50 rounds a day at prairie dogs, using 168 SMK's. The .300 mag I shoot is a bit bigger than the Win mag, so I can't make a fair comparison based on that, but I will say that even with a brake it pounds me just enough more than the 7 mag did, that it is not pleasant to shoot 20 rounds from a bipod with it. My $.02, and it is based solely on opinion.
