a marlin 45-70. its got the range, its got the power, its got the classic look, though a ruger #1 singleshot in 45-70 would also be a good choice. at those distances dont get a magnum they will ruin more meat than a standard cartridge. me personally i use a ruger gp-100 in .357magnum. some argue its not enough but you can argue with a bullet that passes thourgh the deer and out the otherside. double lung shots are the only ticket for the cartridge though, i wont try any other shots. actually anothe good choice for you is the ruger deerfield carbine in 44mag. plenty of power in a light package, and its auto loading if you like that sort of thing
