I'm thinking of buying a rifle in .300 Win Mag. I've gotten pretty decent with the .308 (I still consider myself new) and want to get another rifle, so I figure that I might as well step up to something bigger that will go well past 1000 yards. I've been pretty set on the .300WM but I have some people locally trying to talk me out of it and into a .234 or 6.5 Creedmor and some other 6MM's saying that they are cheaper to shoot and can be shot as accurate at the same distance as the .300WM. What do you guys think is the "prefered" caliber for the 1000-1400 yard mark? A few things I should state also are that I do reload and that stopping power matters to me.
