I have a few 7mm, and one 300winmag. I am considering thinning the herd, and trying to decide between keeping my 7mmSTW sako and my 300winmag 700. Now, I have put a mcmillan stock and trigger job, and complete bedded the 300.
I think I have decided to keep the 300winmag. The 7mm can be generally flatter. But the ability to shoot 200gr trumps my 7mm decision.
