"Glocked" Cases

[ManualF150]

Fellow asked me at the range the other day regarding slightly bulged 9mm cases for reloading after being shot with a Glock (or similar design).

My answer to him, I use my case checker an go thru my brass after cleaning it and sort it. If it don't fit the case checker, I send it thru my LEE undersizing die, then recheck it. The rest, I run through my RCBS standard sizing die.

As always, carefully check the brass for other issues, if it looks strange, throw it out. When resizing always start with your 10% under charge and test a few rounds and ramp up to get proper velocity and function for the bullet.

Hopefully this will help someone who is having trouble with reloading range brass.

I run mine through the factory crimp die. It takes out any weird bulges.

I have a LEE factory crimp die too, but rarely use it. I was going to mention it, but I've had 100% success so far with the undersizing die.

Only time I've had issue was with outrageous Buffalo Bore 10MM rounds giving the smile in the starline brass out of my G20C. That reloaded brass wouldn't chamber in my Dan Wesson Kodiak. I used the Lee FC die and it fixed it.

The only way to really get rid of the glock bulge in 9mm is to roll size. shop product wizard Page | Rollsizer
The machines are expensive and don't make sense unless you compete or load large volumes. . Luckily I have a friend that has one for when I need it.
