I've got two Winchester 94's... one is a mid-70's era rifle I got used for $100 that shoots great, and the other is one of the last ones off the USRAC line before shut-down, still NIB.
I've got a friend that wants to trade for the new Winchester, and he has a Marlin 1895 in .450 that only has a couple of boxes of ammo through it. Trade includes the once-fired brass.
Recoil is too much for him and he doesn't see himself getting into hunting... certainly not for any game that would be best served by a .450.
I've shot a .450 before and while it's certainly a stout cartridge, I can handle it. And, I'd have a use for it as I go out hunting. I could see using the rifle for elk or black bear here in AZ. I certainly have a hole in my rifle pool for it, too. I don't like the idea of hunting with my Mosin 91/30 since the safety is so awkward on it, and that's the only bolt gun I have. The safety is extremely loud on my M14, and those don't react well to using anything over about 170 grains. Those are the two most powerful rifles I own right now, and neither is well suited to the hunt.
What say you, APS? Make the trade? I'm leaning towards "yes" but I'd love to hear from .450 or .45/70 owners and see if yours gets shot, or just collects dust in the corner.
