Do anything to new pistol brass?

New to this. Do you need to do anything to brand new pistol brass? Like re-size or chamfer, tumble clean, etc.? Starting on 45 ACP.

I resize "just to be sure," that and a good looking over of each round. If the brass is pre-primed, I simply adjust the primer pin up out of the way.

I resize to insure the mouths are round, and inspect for deformities.

Resize all new brass. Measure, trim if needed, camfer and debur...Tumble for about 30 minutes.

I don't tumble new brass but do check them for defects and resize. I once made the mistake loading without resizing and had to remove many of the loads because the casing didn't fit the chambers properly. Learned my lesson. Ed.

resize, trim if needed and chamfer/deburr

With the new Starline I typically start with (in pistol calibers), I just start out with loading process after a cursory inspection. That is, in my 3-to-5 (Lee) die setups, start with the resizing, etc., etc.

I have tried a bit of lube on the new cases to help minimize the sticking that can occur with new (Starline) brass and the Lee PT expander--but it really isn't worth the hassle, now that I've polished the expander a bit.

I just loaded some NEW mag-tech,(CBC), brass, 44 mag. Put it through my Dillon 650. I left it set-up exactly like it would be if the brass was fired, sizer, expander and all. I noticed it didn't like to come off the expander/powder funnel. A spritz of RCBS case slick into the case feeder solved that, sizing was easier as well. It needed to have the inside of the cases lubed a bit.

In another loading session, loading some 357 sig brass that I got from Midway. It was primed new PMC brass. Since this brass requires lube, like any other bottle necked brass, I backed the sizer way out as to not touch the brass. I didn't want to take the chance of killing the primers, OR having to move the decapper on a Hornady die!:fire: I figured the powder funnel/expander would round-out the mouths that were a bit out of round, it did.:D

Normally all I do with any new brass is pass the expander through the brass with the die backed out a bit, so as not to have to lube them. This makes the dinged, out-of-round mouths round so it can be inside chamfered IF NEEDED. Bulk rifle brass from remwinchester, I also check the length, trimming if necessary.
