Chamfer straight wall cartridges before belling??? Thoughts

[Djtjr]

Subject says it all. Is it recommended to chamber the inside of revolver brass prior to belling for precision revolver reloads? I am torn between wanting the taper and liking more material to grip the bullet in the crimp grove. Any thoughts helpful. Bare in mind this is for trying to get the most out of a reload not just plinking rounds.
Thanks,

Not necessary IMHO.

Just remove burrs if you trim.

Are you a bulls eye match shooter? If so, chamfering the ID of the case mouth is an option. The only chamfering I do is on rifle brass that is shot 200yds plus. With BPCR reloads, 0.001 to 0.002 neck tension and no crimping - just the bell tapped down

I chamfer. Makes seating those sharp, flat bases oh so easy.

I chamfer outside for burrs only, and inside a significant chamfer (watch out to not knife edge your case). I find I rarely shave lead with a case that is chamfered. Just my 2 cents. rch

I always true the mouth and then inside deburr the interior mouth of all brass to be loaded with cast bullets, before expanding, to remove the wire edge which could shave lead from the bullet. Doing so does not reduce bullet pull and reduces the amount of mouth expansion necessary to start soft lead bullets into the case without damage. The benefit is greatest with bevel-based bullets. I use a 1/2" ball-end mill cutter to do this for .38 Special, .44 and .45, and a 3/8" ball-end cutter for .32 revolver and .30 cal. rifle. Run the ball cutter at low speed in the drill press and just lightly "bump" the case mouths against it.

I do this routinely with all new brass after ironing any bumps or wrinkles out with the bullet nose of a dummy cartridge. You can chamfer about 1000 cases an hour. This step is especially important with thin walled cases like the .44-40. Only a light touch is needed.
