I have a question for fellow reloaders. It pertains to all new brass, but PPU in particular. I've got a bag of 100 new ones. Does anybody prep new brass? (run it thru the sizing dies, chamfer/deburr, etc?) I got in the habit of doing so when I got a bag of Winchester brass and one out of five had the necks kind of pushed in. Thanking in advance...

I usually chamfer & deburr the case mouth, but only if it needs it.
I do NOT trim. I've found that brand new cases often actually shorten on fire forming for the first time!
I do run the primer pocket uniformer/flash hole de-burring tool.

Thanks Shamu. I thought maybe my process with new brass was a bit of over-kill!

I use ppu virgin brass and always size before first use, just because I dont trust that they are all uniform and within spec.
Then check length, primer pocket and flash hole.
Reload and go boom.
shoot em if you got em

 I will typically neck size new brass to be sure the case necks are consistent and round.  Sometimes you will see deformed mouths, dings, etc.  Then inside chamfer the mouth and uniform primer pocket depth. 

F/L sizing is also fine, but I have not had the need to do so (chambers will most likely be larger than the new cases).  Agree with Shamu, don’t trim, unless you are particular about having a uniform case length.

A while ago I loaded up some new Winchester or PPU brass and headed off to the range.  I also a new powder thereby introducing a new variable.  Well, accuracy was terrible.  I had one or two left over rounds which I checked for run out.  The run out was visible just by rolling the cartridges.  

So, my modus operandi now is to expand the necks of new cases in stages and rotating them as I do.  I have a two step expander that I made.  This keeps them concentric and minimizes neck expansion on seating the bullets.  Too tight a neck will result in excessive expansion on seating which will most likely be uneven.

My normal reloading practice is to minimally size the necks without an expander ball.  I can do these things having as it is, a lathe.
