what size ball to use (exactly)

[nick_1]

RTFM Pietta calls for .454 certainly Uberti has their own specs.

I shoot a Pietta 1858. I mold .454 RB and .452 Lee R.E.A.L. for my conicals.

For the Pietta 1860’s and 1858’s it’s .454 every time. That works best for me and mine.

So if revolver shoots really good with a .454 it will still function with a .451? Or vice versa?

Mine shoots good with .454 but only shaves about 80% complete ring. I'd like to try with .457 but not sold locally and haven't got around to ordering any yet. Definitely seems to me a waste of my time to try .451 with mine, but if the OP's chamber specs to .450 then OK to give them a try, I suppose.

I purchased a .454 mold, and a box of .454 lead balls, both worked just fine, I have the 44 Uberti 1861 colt and it is quite accurate with the .454 round balls, hits the target ever time dead center.....

so I pulled the cylinder and measured the chambers with a digital caliper, the chambers were 0.450" the 0.454" ball seems to work very well, cuts a nice ring of lead on loading,
