too chamfer or not to chamfer

[stefofthenorth]

I have yet to get a progressive press and load using a single stage press. I usually do runs of a caliber. Now my shooting has gone up as I am shooting IPSC and IPSC. But after this weekend I have kinda had enough..... I chamfer 1800 9mm casings and sized and flared and primed them. After one broken de-caping assembly and extremely sore hands and fingers , I ask the question how beneficial is to chamfer ? I generally Chamfer my 9mm, 357 and 38, 44mag and 45 acp and 40S&W. Does it make a huge difference. I shoot jacketed and cast

By "chamfer" you mean remove material with a cutter? If so no, no need at all for pistol cals. Just flare/bell the mouth enough so there is no bullet shavings or no crushed cases.

Someone can correct me if I'm wrong but I don't think that chamfering pistol brass makes a difference.

I only chamfer/deburr rifle brass after trimming and I only do a few at a time by hand. A Lyman case prep centre is on my list of things to get.

Ain't got no time to be chamfering straight walled pistol cases! That's madness talking. lol

Well, not unless you're case trimming them... then that's double madness. Just kidding, kinda.

Only chamfer rifle

You mention you shoot both jacketed and cast, for jacketed I would chamfer the brass I use for them and forgo the "bell" stage just as I would for rifle brass. For the cast I would forgo the chamfer and just bell them. Keep the brass separate for their intended use and re-use accordingly.

I read in a manual way back when I first started loading for an old 9mm I had, that one should never chamfer any rimless, straight pistol case that headspaces on the case mouth. It made sense to me then and still does today. I trim and slightly outside chamfer my 45LC, 44 RM, 357, 44-40 cases, and apply a good roll crimp, but never 10mm, 45 ACP or 30 Carbine, which use a taper crimp and rely on the square case mouth for headspacing...........

I have never trimmed or champfered a pistol case.

I only trim and chamfer rifle brass, don't even look at case lengths for pistol stuff.

Why on earth would you even consider chamfering pistol cases? Beyond the fact that it is MADNESS, pistol cases typically split at the neck and chamfering would only hasten that problem.

reloaded about 3k of 9mm and shout 1800 of it and never trimmed or chamfered any brass.
