Way beck in the 1980s when I had a .44 1858, I was told the rule of thumb was Italian clone - .454", ROA - .457". I've never heard where that's bad advice. .454 should give you a good seal on the chamber.
If all you are worried about is shearing a lead ring, .454” diameter balls will work. If you are going for accuracy, suggest you consider the rifling diameter and reaming the cylinders to be .001”-.002” larger, then getting the exact correct ball diameter. You state you are an old time centerfire reloaded, so guessing you will understand. The groove diameters on Uberti’ I have owned and checked seem to measure about .458”. Check and figure from there. Personally have found matching up cylinder, groove and ball diameter will tighten groups up.Black powder (and casting) newbie here (old time centerfire reloader though) I just removed the cylinder from my New 1860 Uberti Army pistol and checked all 6 chambers with a caliper,
0.450" x 6
what size ball should I use to get a good swage on the cylinders ? I see many ball molds at .450 and I see Hornady selling ready made balls at .457
what is the best diameter to use ? I'd like to get a ball mold slightly over .45 and make my own, but dont see any
what do you recommend ?
If I could find a 0.452 ball or mold I would go with that, but dont see any now, I may just go for the 0.452 bullet mold and shoot some of those too, for starters will use the balls .I'd buy a Lee .452 45acp mold. Lose the balls and ram home some bullets.
A gentle chicken plucker honing of the cylinders will be required to get the correct fit.
But it's worth it. You can size them to .451 too. More than one way to skin a cat.
PS: The 160 grain will allow for more powder.
I’ve handled a fair number of technical inquiries from customers regarding $100k pump stations or controls. “Why won’t it do X, Y, and Z?” I typically begin, “Well, if you‘ll turn to page 42 in the manual you discarded all will be made clear.”I don't read manuals.
Why?
Did I create a Dragoon Grenade that has yet to blow up?
I can appreciate that.I’ve handled a fair number of technical inquiries from customers regarding $100k pump stations or controls. “Why won’t it do X, Y, and Z?” I typically begin, “Well, if you‘ll turn to page 42 in the manual you discarded all will be made clear.”
And yes, stock Uberti’s should use a .454” ball in Army revolvers, .380” in the Navy caliber guns. Pietta use .451 and .375”…
I can appreciate that.
My point was the person who brought up manuals did so in a way that made what I was doing sound dangerous.
The unbridled timidity that pops up on this forum over and over bugs the hell out of me. Grown azz men with guns that are afraid of guns. Or are afraid of pushing their guns to see what their guns are truly capable of. Not what the lawyers writing the manuals say their capable of. It's bewildering as all get out.
If someone is going to intimate that something is dangerous, then spell it out. Scientifically.
Don't just make a Did You Read The Manual comment. And not follow up.
