ElKampMaster:

If you handload, I would not worry about calibers turning wildcat. I would go with a .338-378 Wby. Mag. in a Weatherby Mark V Accumark, or a Weatherby Mark V Threat Response Magnum Custom. I have data for a .338-378 Wby. Mag. pushing a 250 gr. Sierra bullet at 3152 f/s, a 275 gr. Speer bullet at 3,088 f/s, and a 300 gr. Barnes Original bullet at 2998 f/s; all three loads will be devastating on elk although I would use different bullets than the ones mentioned (the Speer 275 gr., and the 300 gr. Barnes are no longer made) . I would use a 250 gr. Barnes XFB, or a 275 gr. Swift A-Frame for hunting. For long range target I would use a Sierra 250 gr. HPBT Match King, or 300. gr HPBT Match King. Good luck.
