7mm rem mag vs. .270win

[rem 700]

Factor in the accuracy beyond 100 yards. Penetration, velocity and energy are both extremely over the 270. For deer, the 270 does the trick, but not as fast as a 7mm magnum. These guys don't sound like they have the ability of beyond 300 yards, and the 270 is definitely adequate to drop deer at that range. They have the edge in ballistics, but it comes down to shot placement, where the more experienced have the edge over the powerful gun.
