The .45-70 Marlin lever gun is a great weapon - I have one. It's a nice, handy piece and it's just fun to shoot. If you get one, do yourself a favor and spend a few bucks on a slip-on recoil pad - the wallop it gives your shoulder is brutal without one.
LOL....my brother has a .45-70 barrel for his TC Contender. Up to a point, I'm a glutton for recoil, firm in the belief that Newton will settle the score on the receiving end of what I'm shooting at...but somethings are simply beyond human reason...;-)
