If the wall of that seater stem were a little thicker, I might have suggested putting a chamfer on it. I've done that with some other brand seaters in the past.
As for Hornady, I've had a couple of sets of their dies. Their seater is a poor attempt to mimic the Forster, and their sizer no better than Lee's full length sizer.
I'll clip a few lines from Forster's replies:
1) Do you know what neck tensions you’re loading into or if it’s a compressed load or not? Also, what bullets are you seeing this on?
Our remedy to the “ring on the bullet” issue has been our custom polished seating stem (form attached). We have been developing a prototype stem that we’re hoping eliminates this issue. If you reply with your address, I can get a prototype stem out to you to test.
2) The need for adapting the seating stem profile has been an ever changing revolving door with all the different bullet profiles on the market.
3) We seldom see that the seating stem may contact the bullet ogive at an unsupported portion of the jacket (i.e – there’s no lead under the copper jacket). This is where the ring issue comes from. Our custom polish service lowers the stem contact point on the bullet to a more solid part of the bullet.
