Cylinder chamfering

[andy52]

I'm thinking about chamfering one of my model 14s to make speed loading a bit faster.
I have a PTG cutter but they don't offer a 38-357 pilot, they do offer a 9mm NATO pilot I think that would be close enough to keep the cutter centered. If anyone here has one of these pilots and has used it that way please let me know how it worked before I buy one.

Check SAAMI Specs! The case diameter appears to be the same!

Not sure the case diameter will help much the pilots are for the bore size which are intended for crowning a muzzle, even if they had a 357 pilot it would be just a little loose in the chamber. My thoughts are that the difference between .357 and .355 wouldn't be enough not to keep the cutter centered in the chamber.

I thought 9mm Luger was a tapered case, vs .38 Spec. is straight wall. Better look at SAAMI drawings' case dims, if the pilot centers on the case bore in the cylinder and not the throat.

Brownells offers pilots for both bore diameter and chamber diameter. I've done tons of chamber chamfering on PPC guns. Do the work with the ejector removed then care fully break the corners on each corner of the ejector star. DON'T over due it.

Thank you I found them at Brownells just as you said and ordered one.
