Cylinder bore

[Sorry Dude]

The cylinder bore on my 1851 Navy is .3725 and I'm having a heck of a time seating .380/.36 cal conical bullets, the kind from eras gone. I know the cylinder bore is undersized and would like to have it enlarged a few thousandths. Looking for a gunsmith/machinist that could do this, any recommendations? Thanks in advance.

Others can weight in, what I find puzzling is that the 44 (45 Cal) JD Conical is .460. It does not go into a .454 ball cylinder at all well.

It does fit the ROA decently but that was designed for a .457 ball (bullet).

So were cylinder chambers larger back in those days? In theory that is a direct copy of recovered conicals. Its unfortunate you have to get yours bored out to get to fit. The should offer some size difference.

can the bullet be sized?
