Don't need to chamfer more than once. It won't hurt but it would be a waste of time as you have already put the inside bevel to the case mouth.

Kracky is dead on here but don't forget.....you must check lengths after resizing every time!

If you have to trim to length then you may have to chamfer ID/OD again.

You might take a look at the cases. Sometimes they can pick up a burr during ejection or handling after they have been fired. If you find anything it will not amount to much.

I don't know if there is any real, actual, connection or not, but it SEEMS to me that one of the reasons I almost never have to trim my case lengths when I reload may be BECAUSE I inside/outside chamfer every time I reload.

Don't know if that short-lived little 3,000-degree fire up there is melting away part of the thinnest section of the chamfer off at the very tip of the brass or what, but the two seem to go hand-in-hand. (Chamfering every time, but not trimming.) Or maybe my loads are just not hot enough to cause all that stretching and/or brass flow.

I do trim them all to the same length when they are new before I load them the first time. Surprising how different the lengths are in a given lot of brand new untrimmed brass with some brands.

I'd never thought about checking the length on new brass. I just figured that they were all the same length from the factory. I'll have to check next time.

They aren't all the same length. My experience is that they are all shorter than recommended trim lengths. Most aren't square, either.
Fire once, resize, then clean them up.

Hey Neale, I've never found saving time to be any kind of advantage in Reloading. I'd discourage being in a hurry to get the components all put together. I make enough mistakes along the way without adding a speed-of-assembly factor.

For what it is worth, if you begin getting unexplainable Fliers at longer distances, it could be as simple as a Burr on the inside of the Case Mouth. Of course it could be something else, but "you" have control whether a Burr is present or not.

After each firing, I Trim with a Lee Case Length Gauge/Trimmer which keeps everything consistent. Then I Deburr the outside, Champfer the inside, and then Polish the Case Mouth. I Polish with 0000SteelWool wrapped around an old 22cal Bore Brush. Stick it into a non-powered handle(Lyman or RCBS) and give it a couple of twists back and forth.

Best of luck to you.

Well, I chamfer and deburr every time (but very lightly on those that have been done before), just to smooth everything up. It's funny, I'm fussy here, but most of the time I don't clean the primer pockets (never had a problem not cleaning them). I suppose you could say I'm a little inconsistent.
