My problem is that I never hav enough money
There was an engraved winchester 94 in 38-55 that came through my local gunstore (pawn shoppe) that I fell in love with!! I just couldn't swing it financially. What's this got to do with your question?? Not much, I just wanted to fuss. :-D
Seriously, I'm a fan of the 38-55, I really want one, but I have a 45-70 and won't trade it for the 38-55. So I guess by elimination, I prefer the 45-70 if I can only have the one. It is a venerable old cartridge that, like the 30-06, can be loaded
WAY up or
WAY down. The cowboy is a pretty light rifle for 45-70 but even still can be quite comfortable to shoot with 35 or so grains of 3031 and a 350 to 400 grain bullet, this load is safe for trapdoor, if that gives you an indication. I believe the cowboy is ballard rifleing, which might give some edge if you should want to consider shooting black powder in the future. The 336, I believe to be button rifled, and I have no experience in shooting cast bullets through this type of rifleing. Someone else will tell ya how well that does or does not work.
Man, don't it make you wish you could have both!!! :-D :-D :-D
Well, how did I do at talking a lot and saying nothing!!??
Let us know which you decide, always intrested in pards getting new guns, it helps when I can't get a new one for myself!
