new 45acp brass

I don't care who makes it I size it new or old. I will store used brass and prep it for loading. I store it in a plastic bag with I.D. telling what has been done to it... Even when I purchase the so called perfect brass for the big bucks. I still go over it and give it full inspection.
Hawg, did you have to size only the 15 and the others were good to go. I shoot mostly 308 the brass I get from a friend that shoots 308 match A Max. I F/L size his brass, but for the life of me l can't remember 12 years back I bought new Win & Rem.brass 100 each, if I sized before I reloaded them.

That is how you answer your original question: Do they need to be sized?
In spec: No.
Not in spec: Yes.
It's pretty much that simple. New brass does need to be inspected. I bought 1000 Winchester .223 cases one time and found two in the box that never had the flash holes punched. This is one kind of defect commercial ammo can have that reloads never have (because they were already fired once).
That brings me to point out the bulk cases you buy from an ammunition maker, like Winchester or Remington, are the same ones they load in their machines to make commercial loads. That's why the size has to be right as they come, less any rejects.
Bottleneck rifle cases are a little different from handgun brass because its necks and shoulders are softer from the extra annealing at the end, so it picks up case mouth dents much more easily than handgun brass does when transported someplace in bulk. All that shipping company package handler throwing and dropping can take a toll on soft case mouths. So you may need to de-dent some of your rifle brass, and may need to size the neck, too.

Three things are different. One is that many auto cases, 9 mm in particular, have tapered sides, but the carbide sizing rings most of us use these days make them straight, which means tighter. The 45 Auto, though, has less taper than the 9, and I can't say I've ever noticed a serious difference using new or resized brass with it. Then again, I wasn't looking for it, so I could be wrong. Another difference is the brass gets harder as it is worked and more springy. (This can actually lower bullet pull because resizing doesn't any long size it down as far. I used to pitch R-P cases because they would get so springy they wouldn't hold a bullet at all after resizing, and that would happen in just two or three reloading cycles. That was using a Lyman carbide die. The Dillon die I use now is tighter and overcomes that.) The third thing is residual fouling is in most cases that has a rough surface.
