I've pretty much decided my next rifle will be a lever gun. Now I'm trying to decide which caliber. I will say I've always wanted a 45-70, but don't want the cost of factory ammo to keep me from shooting it. I will be using it for general shooting and hunting a thick swampy area from a tree stand. Shots would generally be under 100 yards, with an occasional 150 yarder on deer. Would I better suited to a 357, 44, or 45 colt? I've got a ruger super blackhawk in 44 mag to use for hunting, but also a SAA clone in 357. Also any opinions on rifles? I would like something I can mount a forward mounted scope on as well. Thanks for any help.
