9x19mm case length in inches
 
I have never bothered reloading 9mm because I could buy practice rounds cheaper than I could load them. I now need to load some. 9mm max case length is .754" I am finding length variations on mixed once fired brass from .740" to .752". Unfired Remington brass was .747". Fired Remington is running .747" to .749". 19mm=.748" What is your minimum case length? Fiochi and GFL are running short while Winchester is all over the place. I have been segregating the brass to over and under .745"

WAY TOO WORIED ABOUT NOTHING. I do not bother checking case length of handgun cases. There is a substantial amount of tolerance there. Load em and shoot em. In over 35 years of handloading I have NEVER trimmed a handgun case. Bottleneck rifles are a completly different game.

It you don't care about getting a consistent taper crimp, do what the moderator above does. It you care about making quality reloads, trim them all down. .744 is the minimum.

I am more used to rifle cases. I have been loading quite a bit of 38spl and they have not been that inconsistent. Probably chasing my tail since they were all fired. I was mostly concerned with the crimp being consistent. I use a separate taper crimping die. I will eliminate anything under .745" and trim or toss anything over .750". Probably not enough brass to worry about in those sizes.

As others said no worries. I've never measured my 9mm cases either. Make sure your COAL is correct and start at the minimum charge and shoot em.

Huh? I do not trim and I crank out ammo that shoots at least as good as I do. And for your info, I am a B class IPSC shooter, NRA/FBI firearms instructor. You will not be able to see any appreciable difference by succumbing to your OCD urges.

I set my trimmer to .748". The cases are picking up .003" on sizing so not many rejects. I am trimming anything over .750" and culling anything under .746". I figure I can live with +-.002". Only culled 4 cases so far. I am loading 1k shft ammo. 124 grain HP. Not for carry unless everything goes to hell.

I don't load and shoot as much as I used to with my pistols but I just load and shoot with a Lee Progressive press, no trimming and no problems.

WOW! I am impressed!! It has nothing to do with accuracy. It has everything to do with safety. Go back and read your manual if you have forgotten the reasons for being OCD with semi-auto reloads. But hey, it's your world and I just live in it. Nothing has happened to you in 35 years so it should be safe practice for everyone else out there.:rolleyes:

Buddy I've been loading pistol rounds for 30 years myself. I've measured pistol brass of just about every caliber and none of them have ever exceeded max length. In fact 90% of the time they aren't even long enough to trim. A few thousandths of an inch isn't going to make enough difference in your crimp to amount to anything. It certainly isn't going to make it unsafe. I suggest you pull some bullets on new cartridges and see for your self that even factory loads have brass that varies in length. If you want to make sure that every piece of brass you load is exactly spot on good for you but it certainly isn't necessary.
