I have an Uberti 1858 Remington w/a .45 Colt conversion cylinder. The Uberti specs are; bore .440
groove .458
wide .10
twist 1:18
Keeping all this in mind plus the fact the original load featured a .454-.457 136gn roundball, how should I proceed to achieve decent accuracy? I was thinking of using 265gn lead for a .455 Webley, or should I try and find a lighter bullet(150gn or so) in .454?
I would appreciate any help at all, most threads deal with powder loads and I'll go there after I figure what bullet to use.
