flash hole

[Flinthills Dawg]

How many of you that load your own with reduced charges deburr the flash hole on your brass?
Do you think it is necesarry? I deburred 200 brass and loaded them have not gotten to shoot them but in my beady little mind it will make a difference.

Dawg, I do very little to my brass unless something catches my eye to merit it. About the only thing I do is with new brass, I chamfer the mouths the first time it's to be loaded. After that, it's just shoot, clean, reload...........Buck

Mr. Dawg
 I have yet to chamfer the flash hole in any of my brass but I have trimmed the mouths after cleaning them then went on to reload never had any trouble and I have been rolling my own for darn near a year now.
 I do find, however that some primers burn 'cleaner'  than others.

I was just thinkin with the reduced charges the more uninterupted flame you can get into the case hopefully a burn back does not happen and cause an oops on the shootin line. Dont want to be known as the moron.

No-one, will fault you fer bein cautious, in fact they'll shake yore han 'n slap y'u on th back, "better safe than sorry"
maybe a cliche but it  is dern near th "golden rule" when it comes ta th shootin sports. So do what ya hafta do to be comfortable with yerself an "sure as shootin," y'u'll make everybody comfortable. In mah experance,with a tight sealin bullet burn back is minimal, if at all.
 'nother thing is ah use "titegroup" by Hodgdon, neva had a misfire, Ah'm not askin thet y'u  switch yore propelent, jes thought Ah'd pass thet along.

You're messin' with pistol caliber stuff if you're shootin' CAS. Precise preparation of brass isn't necessary.  Basically, all you need is plinking quality ammo.  Just about any powder bullet combination will work.  Some are cleaner than others is all.  Over the years I've tried them all and that's the only difference I've found.

Where folks get in trouble is using loads reduced below the powder manufacturer's specs.  Even with low end loads some calibers out of Winchester clones are gonna give you a breeze in the face when you drop the hammer.  The flash hole has nothing to do with it, there's simply not enough pressure to seal the chamber.

All I shoot in CAS is Black Powder these days.  Fill the brass, smash a bullet on it and forget it..........................
