So, I have been loading all my own rifle ammunition, but never seen the need to load pistol as I do not shoot in nearly enough quantity. I recently came across a large quantity of range brass at scrap prices, (see my add for .40 brass for sale if you want some, lol), so I figured I might as well process and load some .40. With brand new (Lee) dies it seems as though it is under sizing the base of the case, just above the case head. On a clean, but not polished case it is hardly noticeable, but on a polished case it is easy to see (picture will be attached). There is no abrupt crease, but can be felt with a fingernail. I do not have a case gauge for .40 yet, but they do drop in and out freely from the chamber of a USP and Glock. Dies adjusted per Lee instructions. Since I haven't been loading any straight wall pistol cases I figure I should ask what you guys think? Normal? Am I doing something wrong/stupid? Something up with the die?
