Handgun case length
How important is handgun case length? I know it's very important in rifle cases, but does not seem to be as important with straight sided handgun cases - is that right?
I measured 35 once fired 9mm cases and the average length is .746" the range is 0.739 - 0.755. I know it affects case mouth expansion - long cases get more bell than short cases, and I suspect (but not sure) it affects crimping.
I haven't loaded very many rounds, but so far I have not noticed any problem with crimping - but maybe I don't know what to look for. The few rounds I've fired (10) didn't have any issues. They worked as good as the factory rounds.
All of my cases are coming from an indoor pistol range and I suspect every brand of ammo known to man is fired there. I throw away all the steel cases and the ones that have been stepped on or have finger nail polish on the primer (I think that means they were reloads). Other than that I just sweep up the floor and put every thing in a bag and make no attempt to sort them by brand.
I would be interested in knowing if that is a problem, and if so what to do about it.
