Dumb Handgun Ammo Reloading Question (Noob Inside)

[sidewaysil80]

So today I set up my Lee turret press and began setting up the dies for 9mm. Everything was going fine until I seated my first bullet to fine tune/adjust bullet seating. My question is there is a bulge forming in the middle of the cases, are the cases not being sized properly? Is this normal? If it matters the OAL is coming in between 1.070-1.075, it seems that if I set it to 1.075 after seating a few bullets it gets a little shorter. I'm using misc. 9mm brass with Precision Delta 124gr jhp bullets...

The line is the bottom of the bullet. It's fine.

The line is the bottom of the bullet. It's fine.

I figured as much, I was just comparing it to factory new ammunition which didn't have the line/bulge and figured I'd consort with the experts. What causes the bullet line to appear on reloaded brass but not the new stuff? Thanks for your help by the way!

Its fine. The 9mm is tapered and the resizing die is doing its job just fine. They should feed and function without any problems.

Thanks guys! I appreciate it!

Try the plunk test, but they should be fine. As already said, 9mm is a tapered case, it is common.

If you're concerned about the "bulge", you could use a newer Lee carbide crimping die for 9mm. They actually have 2 carbide rings. The first one is at the bottom of the die, and its function is to essentially FL size any loaded brass. If you have a bulge that might interfere with chambering the round, it will squeeze it down to specs. The upper carbide ring does the actual crimping of the bullet to the case. This has given me some satisfaction and confidence whenever I have a bulge. Bottom line is that none of by pistol reloads have ever failed to go to battery. Good luck.
