Re: Bullet Seating Trouble
I get this with both my Lee and Hornady dies. With mine it only leaves a slight mark...no indentation or distortion on the bullet at all (I can't feel it), although it is visible. Since I'm too cheap to buy a comparator, I keep my seating depth consistent by measuring from cartridge base to this mark instead measuring off the inconsistent bullet tips. Not perfect, and probably not as good as using a comparator, but it works well enough for me.
If your die is actually distorting the bullet beyond just cosmetically, I'd say get on the phone with RCBS. If its just a mark...I wouldn't worry.

Re: Bullet Seating Trouble
Ya the marks are just cosmedic and they dont dig into the bullet. Now i am having a problem with Barnes X 250 gn Bullets getting stuck in the seater die.

Re: Bullet Seating Trouble
Now don't take my advice exclusively on this one, but that sounds like you need a new seating stem....Or less neck tension (assuming you're neck sizing).
Wait for someone else to chime in on this issue and give a second opinion before taking my advice.

Re: Bullet Seating Trouble
I had a seating die that left a ring on the bullet. I ended up coating a bullet tip with release agent and then put a dab of JB weld on the seater stem to make a perfect mold of the bullet tip.
Problem went away

Re: Bullet Seating Trouble
Take the top out of the die and you will prob have to do some polishing to it. Just take a bullet and try it and you will feel it sticking a bit just polish it untill you dont feel that anymore should get rid of your problem.

Re: Bullet Seating Trouble
Chuck a bullet in your cordless, swipe some fine lapping compound on it and
run it in the seater cup.

Re: Bullet Seating Trouble
I had a seater stem in a set of Hornady dies that would leave a ring around the bullet so I mixed up some MarineTex and created a custom seater stem matched to the bullet I was using. No more marks left on the bullet after that.
