Ring on bullet

Usually that happens when you are crimping at the same time you are seating the bullet. As it crimps it requires more downward pressure. You could try not crimping while seating the bullet and then use the Lee Factory Crimp Die as a forth step.
 
I did the plunk test, and its exactly the same as the Federal round. I also noticed on my carry ammo that each round I have actually chambered, has the same markings on the case from sliding on the feed ramp. So I think I'm good with this. If anything I may polish my feed ramp a little to aid in feeding.
 
What you can do to stop that ring is to fill the seating plug with a bit of wax and seat one of you bullets in it to remove the excess. The wax will seat the bullet right at the plug contact spot and give the seating plug a bit more surface to push against the bullet.

It also looks like you are using just a bit to much crimp. You have to remember how the 9mm seats and it seats on the case mouth so over crimping will make it seat deeper.

You COL is fine. Others have given you the spec length but some gun brands will not seat the spec length. You plunked it so it will chamber in your gun so ther is no need to get the gage.
 
The ring is being cause because you are crimping too much during your seating step. That causes the crimp to be formed and then your trying to push the bullet in the small case mouth, needing more force and making the ring. Back the body of the die out and the seater stem in to back off the crimp some. If you have a 4 die set, might as well back the body of the die out as far as you can, and have the seater stem almost all the way in to prevent your seating die from doing any crimp at all, do all the crimping on the 4th die
 
Yes you should definitely be able to do that. Give it a try. With sometimes finicky 9mms it often takes various die combination settings to get things satisfactory and looking good as well.

Personally, I would buy a case gauge. They're handy. Yes, you can use your gun barrel, but I usually make a lot of rounds when I reload, and I can sit out on the patio with a box of ammo, my case gauge, and can plunk test them pretty quickly. And then I don't have to reassemble my gun. Maybe it's lazy, but the case gauge is handy for me. And it has been milled to a gnat's a$$...it's dead on for spec.

If you're putting an unscratched round in your gun and chambering the round, and then ejecting it and now it has a scratch, it sounds like you maybe have a rough bit on your feed ramp or the magazine.

No skizzums the ring is because the contour of the seating plug does NOT match the contour of the bullet. His crimping to hard just makes the ring deeper.
 
Uncle Ludis....Once you have your seating die set and your first round plunks it is set no need to replunk. The gage is useless if you shoot a Walter.
 
I hate to add to all this....

Could it be that your powder through/expander die is not set correctly?

If not expanded enough, there would be more resistance to the seating die to get the bullet started into the case mouth.

Just a thought...
 
As you make your rounds inspect them and you will find the cause for the bullet ring... It is a natural habit that all loaders should do.

Take a piece of fine emery cloth to polish out your seater and ramp as others have mentioned.

The bullet likely will leave shavings that isn't good for the die or gun.
The cases won't last long with continued damage and you don't want to have rounds jamming in the gun.
 
I backed the crimp out in the seating die and just do a crimp with factory crimp die. The ring is barely noticeable now. All of my rounds are at COL of 1.125-1.127 with 5-5.1 grains of Autocomp with Remington bullets. I shot 10 rounds through my Glock 19 at the range today, no feeding issues, they all went bang and I didn't blow up my hand lol. Thanks for all the replies. There is nothing like just going out and finding out what works and what doesn't.
 
I only mentioned backing off the crimp because I did the same thing when I first started loading. I had the stem baxked out way too far and was using the body of the die way too much. it was causing the crimp to happen prematurely to the bullet being seated. once I backed the body of the die out some and set the stem in some, the ring went away, so it was obviously being caused by too my force being needed to fully seat the bullet.

just my .02, disagree if you want, it was just my personal experience. I deformed many XTP's that exact same way. you don't need to remove any crimp ring from the seating die, just back the die out of the press so far that you are not even touching it, the seater stem will go deeper than where the crimp starts. I only have experience with LEE 9mm dies BTW, and this is how it works for me. then you can do the final taper crimp/flare removal with your fourth die.
 
All I did was let everyone kno what worked for me. My ejection was pretty weak but was still able to cycle my 19. So probably go up a few grains and see how that works for me and do some accuracy testing.
