With bottleneck rifle cases. Just curious if you chamfer and debur after every resizing even if you don't TRIM? I have since day one but wondering if it's really necessary.
No need to deburr unless you made a burr, by trimming.
If you chamfered sufficiently last time you deburred, you shouldn't need to do it again until you trim, but sometimes I give it a gentle touch with a VLD chamfer tool just to clean it up.
I check the overall length, and if the don't need trimming it's really quick to take a look at the edge and chamfer if necessary. A sharp edge on the inside will want to shave the bullet when you seat it.
At times, if I run my brass through my rotary tumbler for a long time the case mouths get peened and shave bullet as they are seated. A quick chamfer cures that.
Every piece of rifle brass goes through the Giraud ( one step trim / outer chamfer / inner chamfer) and gets whatever trim and chamfer it needs. Some need more, some need less, some just get kissed - but they all go through the same process.
I do every time with rifle cases, mostly because of tumbling cases to clean them dings up the mouths of the cases. After trimming is a must. After tumbling with me it's inside only.
I mostly use an ultra sonic to clean but I tumble after drying to get the tarnish from my drying process off.
LOL! No, just use a dry rotary tumbler most of the time. I built it back in the early 1990's and it can be a little hard on case mouths if I put to many in there at a time.
I'm sure your using a vibratory tumbler as I should be, for post tumbling.
