While reading the basics of reloading in the Lyman 49th, I read a statemant that I should resize new brass, does that apply to new primed brass as well?
Some folks want their new virgin cases expanded to larger dimensions than when unfired so they're closer to chamber dimensions before they resize and reload them. There's nothing wrong with this. Benchresters do this often and use an old worn out barrel to do it saving their hummers for matches.Nothing like measuring before and again after, then there is the fire to form, when I fire a case I eject once fired cases, others eject fire formed cases, point?
Some folks know that new cases shoot just as accurate as (sometimes more accurate than) fired then reloaded ones. But their case mouths are not all that uniform. Resizing just the neck and/or mouth makse the neck more consistantly hold bullets with the same tension as well as being very straight on the case. So they want have accurate ammo to shoot even if it's just to fire form the cases.Why size new cases if they are going to be formed when fired?
