Here's another thing: if you're shooting hard-cast bullets and Black Powder, your accuracy will suffer. Hard-cast and smokeyless is fine.

Gday,
Some advise would be good.
Iam the proud owner of an 29 in barrell Armi San Marco Sharps74 in 45-70 I use a round straight out of Mike Venturinos books Lyman 457125 520 gn projectile, SPG lube, sized and lubed on a Lubamatic to .459, 61 grns of Swiss no4 1.5 FG through a drop tube .030 cardboard wad in WW brass using a federal 200 primer. I get only average results at long range. I have measured the lands and grooves at the crown of the barrell and Im pretty sure that my barrell measures .453 maybe .454 My projectiles are .457 so the question is how will the larger projectile work in the barrell accuracy wise. I dont get particularly bad leading so Im guessing the larger dia projectile is compressing in the barrell. Any comments??

If you are using a caliper to measure the inside of a barrel, the flat faces on the caliper will measure a little small because the faces are flat going into a curved surface. You need an internal mic if you don't slug the barrel.
My Pedersoli shoots 0.458" cast just fine.
