I have a Winchester Sporter in .300 win mag. Its been a good gun so far but after playing with it, about 1" is all that I can do. I am going to send it in to get blueprinted and while there I'm thinking of having a new barrel put on it. The decision part is whether I want to stay with a .300 win mag or go to a 7 mm rem mag. Is one going to be better than the other for hunting (mostly deer and elk) and just shooting out to 800-900 yards?
