So I'm newer to reloading. Not new to owning guns but reloading specifically. In any case, I have a Redding T-7 press. Got a bunch of 9mm brass in good condition once fired.
I notice that cases can vary in length from 0.0.745 to like 0.754 with the brass. This seems to be the acceptable length, but I'm loading Berry's 124gr bullets to A COAL of 1.16.
If the brass is different length, wouldn't that affect the case overall length? Perhaps I'm wrong and it doesn't, but rather it affects the seating depths. From what I understand it does NOT effect coal but rather the bullet is more or less unseated; this must change pressure somewhat?
In any case, I'm super paranoid reloading.. I'm worried something is going to blow up. I know this sounds crazy, but I'm loading these Berry's 124gr with 4.9grs of powder from VV340. There is no load manual that uses this exact bullet with this exact powder, but I've been using Gordon's Reloading Software. With a coal the pressure at 4.9grs VV340 is below the max threshold by a decent amount.
I've fired some already and I notice no signs of overpressure and a velocity of around 1100fps pretty normal for 9mm.
Anyway, I'm noticing case overall lengths of anywhere from 1.165 to 1.6 to 1.55. Should this be a major cause of concern for handgun ammo? Am I being overly paranoid?
