Bullet design doesn't fit seating stem

What is an easy fix for this? Mostly just cosmetic but it bugs me. Call RCBS? Can I modify it?

I have ground down a seating and also used epoxy to make a flat seating stem.

I have but a piece of cardboard/paper over the nose when seating then trimed it.
worked fine.

It just makes the stem shallower so it does not contact the bullets in that area.

JB weld was a favorite for curing that for a while amongst casters and reloaders.

Try some JB weld, it has a reputation for fixing that quite well.

I too hate that ring. Bugs me to no end.

Ha ! there is your answer JB Weld.

I got that with almost all of NOE's top punches, but fortunately they are made of relatively soft Al. and I was able to take my jack knife and relieve the edges,
all is well now.

You can also just whip up a new one in the lathe. I did that for my 300 BLK, I grew weary of the little ring.
For some reason the manufacturers like to leave a sharp edge somewhere in the searing stem.

To much neck tension?

I guess if the crimp comes on to soon that would also exacerbate the condition.

If yer woman hears about giving rings to boolits ya could be in the dog house.

dig around in your old pile of rcbs seating stems and find a flat one and put it in there.
barring that a wad of aluminum foil will fill in that rounded portion.
but that's ugly.
I think your stem has a poor finish on it, I'd lock a couple of nuts together on the stem and spin it in my drill and use some crocus cloth wrapped around a pencils eraser to clean that up.

A little JB Weld should work! This bullet has a pretty big flat on the nose. This should work well. Thanks guys!!

Not certain if he still has them available, but at one time Buckshot made hollowed-out seating stems that could be filled with 2-part epoxy and then nest a bullet coated with release agent in your sizer.

Long ago I ground off the ridge on my 38/357 wadcutter seating stem to make a true flat engagement surface. Marred bullet noses REALLY annoy me.
