11 degree forcing cone

Has anyone ever chamfered their own forcing cone? Looks like Brownells has the kit to do it and it doesn't look too difficult (it says here in fine print). If you have done this yourself, I'd like to hear your tips and suggestions before I order the cutter.

Thanks

I have been doin this for years and it works great. However, most revolvers come, nowadays, with adequate forcing cones.

Thanks. I just had a Cimmaron pistol rebarreled, and the forcing cone is pretty abrupt, so I thought I would smooth it out a little.

I've done a couple of them this year. I rented the kit from an outfit in Montana for half the price of Brownell's kit. 4-D Reamer Rental or something close to that.

Won't need any luck.... just make sure the centering cone stays put while you turn and turn lightly in only the cutting direction! It is easy to cut to much to fast....

It worked!! I was really surprised how easy it was to re-cut the forcing cone. In fact, I re-cut four pistols in under an hour yesterday. The Brownells kit worked flawlessly. Now to get to the range...

ScatterShot: I just got the Brownells kit for finishing off the pistol's muzzle, first squaring then the 11 degree crown. Am I looking at a handful or should this go just as easily as the forcing cone operation? Smithy.

Should be a piece of cake. The cutter cuts pretty fast, so stop and check your work after a few turns, and you should be fine. Be sure to use plenty of oil.

So, how did it go at the range? Any leading problems? How were the groups?
