I've been letting the load, not the gun, dictate what goes with me. I have a lot that I am TOLD will kill deer, but you never know until you shoot them. So far this season, that has involved a .300wsm (Nosler BT, Varget) and an 8mm (Barnes TTSX, IMR 4895). Next up will be the savage (.308) or the Mosin Nagant. Not sure which, but the loads need to be tested on deer before I can tell people what my "favorite deer load" is, which will certainly happen between now and next season on this very site.
Seeing as I didn't answer your question... I'll be using a remington 700, an AR 15, a VZ24, a MN 91/30, and a Savage 110.
