Mind you I don't own one but a buddy has a 45/70 which is the same thing and it ain't bad at all.
That brings to mind, why would they make a Encore barrel in 450 Marlin when the 45/70 is the same thing? I know some may say they're not but the only reason they made the 450 was so you wouldn't use a fullhouse loaded 45/70 in and older firearm that can't take the pressures.
Now I do own a 45/70 Marlin lever gun and I've loaded some rounds for that baby that I wouldn't shoot out of a Contender. :lol: Guess I answered my own question huh?
