I have both in Handis. Two .45-70s and one .45LC. My greatest uncontrollable factor here is range. I never know where a target will appear. The Colt just can't do it. It's fine to perhaps 200 yards, but sometimes I've gotta go over three. No, the '70s ain't point blank, but I've shot them enough to have a pretty good idea what holdover should be. You have to know that 99.9% of my hunting and shooting is here at home, so I have a pretty good idea of distances and holdover. A lot of times I'll take out a .45-70 just to try a pigeon or starling at 300 or so. Most times I miss, but I learn.
I did blow up a couple of crows not too long ago at long range one each with a .45-70 and .38-55. That's what it takes...trial and error. I would think that if I took the time to shoot the .45 I could learn its rainbow too, but I'm lazy and like it where it is.
hand gun compatible ammo to me is what the 45lc has going for it
About twenty or twenty five years ago a friend of mine who owns a Sporting Goods Store had a pair of matched .45-70 revolvers. They were huge. I never asked or knew what became of them. About a year ago, I met Kevin Erickson, Luce County Sheriff at a local gun show. You've got to understand Kevin is a long range handgun expert. I asked him if he knew who bought them. He said a buddy of his bought one. I asked if he ever shot it. He replied "Yes ONCE." 'Nuff said.
