Hey guys! This is my first post on any forum so be easy. I have been a hunter for many years but have recently been interested in long range shooting. So I need help in narrowing down on a "all in one" perfect caliber rifle for both whitetail, aoudad, hogs, & long range target shooting amongst our competitive group of hunters. I would like to round to be capable to take down a whitetail at 500yds if I can ever get that good. I have been on this darn computer long enough looking for information to help me with my selection my girlfriends about to kill, or hopefully find a friend. I have narrowed it down to these selections: 6.5x284 Norma, .257 Weatherby Mag., .270 Weatherby Mag., .30-378 Weatherby Mag., & 7mm Rem Mag. I have yet to shoot any of these calibers so not sure on the recoil but would like something smooth, and any caliber I get will have a muzzle break. Look forward to hearing what you guys have to say. I appreciate it!
