Recoil is moving my balls ...

[junkman_01]

That is the question I have. How would they, back in the day (1860s or so) have chamfered the mouths? I know that it was done, 'cause I see it in my 1851, but would it have been done after production, during...or what? Do they (or did they) make boring tools that are tapered?

pohill,

Chamfering the cylinder chamber mouths is easily accomplished with a chamfering tool. What you were describing was tapering the chambers. I suppose it could have been done, but I really doubt it was done that way.

I have chamfered all the chambers on my C&B revolvers to ease the loading of hard alloy round balls. I see no drawback to it, and, according to the quote you posted, it may be very beneficial and correct!

Maybe you're holding it wrong.

Yeah, maybe - I'm not sure what I meant. I was thinking that maybe they used a tool that widened as it bored into the cylinder (if you can picture what I mean). So, they bored the chambers into the cylinder, then went back and chamferred it?

It was probably done in one step with a boring tool that also had a chamfering cutter on it.

i had this problem

and i just switched bullets , the hornady 255 gr.454 cowboy bullet in my r o a never creeps as long as i seal the chamber with cva grease patch,also the lee 220 grain tapered bullet works too,when i bought my grease patch from meiers the check out girl asked what the stuff was for,and everyone cracked up when i told her i needed to lube my balls

Junkman 01, I have such a drill bit. It is common and not at all unique. It is cone shaped with a point where it first contacts and enters the work, at one end, and a wide base at the other. When the bit is removed from the work the entrance is now wider than the end of the hole. Actually I have two. One has a continuous expansion. The other has stepped enlargements. I cannot imagine a revolver chamber designed with a continuously expanding hole as a good idea.

As to the original question, I too lightly cambered the chamber mouths but in an effort to dispense with the aggravation of the shaved lead rings. Still have them. They are still a nuisance. But according to Makos, a needed one. I think he is correct, but I would do it again.
