Dang good advice from Amp44... although some who replied here talked her down, I won't hold them in contemp. When you can hunt whitetail deer in open country where the deer are larger bodied or the distances may be further then the 7 MM Rem Mag is the one that gets the call... When I say Larger bodied deer and further distances I mean just that,. I've shot deer with the 7mm rem mag at close range and it really wasn't abusive like some here have suggested,(wonder how many here have actually shot whitetails with a 7mm Rem mag),. It's in the weight and the bullet style you choose to use in this caliber. I've made worse mess of deer with decent shot placement with a 30-06 and150 grain bullets.
Thanks for coming!
