Look at it this way, what do you plan to hunt with it? Obviously you have other rifles, so this is to compliment what you have. I would stay 30 cal for strictly a deer gun, noone can argue the successes had with a 30-30, I really like my 307 for deer and blackbear. The 35 a close second. If you plan on hunting anything bigger I say go with a 45 cal either the 45-70 (my preference) or the 450.
