Your cases stretch so as to need trimming?!?!?  I have not loaded much 9mm, but I have stuffed a crapload of 45 ACP......... never had a need for the Lee trimmer dealy I bought: all the cases are the same length, even the ones that have been fired so many times you can barely read the headstamp............

I scavenge brass wherever I can, and have found the stuff to be all over the place in terms of length.  I find in the long run it is more efficient just to sort them by headstamp and then trim them all to the same length, rather measuring each one and sorting them by length.

The other thing I didn't go into was that consistent length brass makes for a consistent crimp after the projectile has been seated.  The way I use to determine if I am properly crimping is to take the barrel out of a Browning Hi-Power, place the round into the chamber, and press lightly with my thumb.  If the crimp is correct, the round should fall out of the chamber when one upends the barrel.  If it sticks in the chamber, there is not enough crimp.

Here's an interesting article on 9mm reloading that shines a bit of light on having the cases all be as close as possible to the same length:  http://www.leverguns.com/articles/taylor/9mm_reloading.htm

Max Cartridge Gauges work fantastic, I have three calibers. All Wilson's. Check every round the go no go tool.

Check all critical dimensions of straight wall cartridges - mouth diameter, base diameter, rim thickness and diameter, case and overall length and bullet diameter.

I also bought those when i frst started reloading....... before I figured out that I could just use, you know, like,  the ACTUAL chamber they would be fired in for the same purpose........

Yes your barrel will work, i still prefer the Max Cartridge Gauge.
The firearm chamber does not measure the max. cartridge length.
These precision made gauges allow the reloader to check the case length, diameter and overall cartridge length of pistol ammunition. This inspection is considered mandatory for those who want ammo that must be reliable for their competition or defense.
They are just plain easy to use.

Whatever your way of measuring your finished ammunition as long as you are measuring is my point.
