Keep an eye on your powder throughs on that LEE Turret press. I have the same press for pistol rounds and when dropping 5g of Titegroup, I literally flick the powder drop before each round to ensure it drops into the disk. Prior to doing this, I was getting squib loads on my .357 rounds - luckily, I caught each one simply by sound, as a few of those squib bullets didn't exit the barrel.
As I am in the midst of picking up my first 9mm, I have been reading a lot on reloading this new cartridge. Due to lack of supplies, I may be using CCI 550 primers - and from what I've read, it won't matter with this cartridge.
