Chamfering Revolver Cylinder Charge Holes

[Just Tripp]

Anybody here done this himself? I’ve read a few pieces on doing it yourself and watched a few videos, so I should be an expert now, right 😁? I’ve looked around, and 4D Reamer Rental rents the cutter, pilot, and T Handle for $30 for a week. I have an old beater that I’d try first. Anybody done it?

If the cylinders are not shaving brass slivers off you don't need to do it.

But to answer the question, never done it....never really got past seeing chamfered cylinders as a "non problem" demanding a solution.

Done dozens..................

I have paid to have it done.
Coupled with conical point Boolits, reloads are very fast and forgiving.

Thanks, gentlemen. I may give it a try. I’ve owned guns that were chamfered and I liked that little extra ease with speedloaders. May give it a go.

Works wonders with wadcutters!

Chamfering the rear of a cylinder, (the mouths) can be tricky w/o the proper tools & stuff.
I shoot revolvers in USPSA competition, and it does aid in speed reloading. I prefer to allow someone with tons of experience AND the tools to do the work. There is a guy here in NC, goes by "DougGuy" on the cast boolit forum, that does the work, does it with a quick turnaround time, AND very reasonable. Especially if you don't want a ruined cylinder.

Now, as for doing the throats in a cylinder, I've done many, and have the proper tools for that. But Doug can also do those as well. He uses a hone instead of a reamer.

I recommend you remove the cylinder and mail it to Joe at Mojo custom guns in Michigan.
It will be perfect.
This one is setup for moon clips so the entire mouth can be chamfered.
Rimmed cartridges are a little different.

Bring it by next time you come. I'll do it while you wait!

Yes, I have the tools for 38-45 cal. I does help speed up the reloads. I sent my 929 cylinder to TK Customs because it is titanium. It was to tough to do by hand.

Per @contender recommendation I just went ahead and had Doug Phillips chamfer the charge holes on a model 66-8 and a 65-5. He also honed the throats to .3585” on both while he had them. I had him go light on the chamfers, particularly the ejector stars. I’m very pleased with the results. Even just a light chamfer made a big difference in getting a speedloader in the cylinder. Even wadcutters. Honing/reaming the throats made a nice difference in groups, too. I‘d certainly recommend Doug if you want some cylinder work done. Fast turnaround and great communication, too.

As I mentioned, Doug does do excellent work.
