I have lots of guns suitable for hunting. The one-size-fits-all for me is the 30.06 in 180gr. Having that said, I've been hunting a lot of years and to bring in variety, I like to go out in early season with new, old , or milsurp rifles. I'm not fussy about what I shoot for whitetail doe season and you can usually get pretty close to them. SKS, MN 91/30, levers, Mausers, shotgun/slugs, ect. For serious and big animal hunting, its 30.06 all the way. It would be painful for me to see trophy game get away because I was carrying a pea-shooter or something under powered in way or range and/or energy.
