I have a chance to pick up a used Browning 1886 chambered for .45-70. I 've always wanted a .50-110 1886, but can't really afford an original. If I rebarrel this Browning to .50-110 what other modicifcations will I need to make ? A new carrier / cartridge lifter ? I know the big .50 is longer than the .45-70. But if it's too much trouble, can a .45-90 be done any easier ?
Or am I just away my money ?
