I’ve only ever lapped one stem and that was on a RCBS die. Usually I just use the VLD stem from Redding and never have a problem.Polishing won’t effect established load. You’ll have to disassemble and reassemble the die, so you’ll just have to re-setup the die.
Disassemble the die. Chuck the seater stem into a drill. Wrap a strip of sandpaper around the end of a qtip, start the drill, work the qtip in and out of the seater stem where it would contact a projectile. I usually do 400 grit, then 600, then 1200. Then polishing compound on a qtip. Or just 0000 steel wool then polishing compound if you don’t have a bunch of different grit paper laying around.
The alloy that Hammers uses does seem to stick more than other projectiles. Lucky for me, the sliiiiiiight visible rings I still get don’t bother me at all. If your OCD really can’t take it then lap like @cahunter805 mentioned. Which I believe would be using a projectile with valve lapping compound on it instead of the qtip with sandpaper. Then polish it after lapping. This is more aggressive as you’re actually trying to change the shape of the projectile bearing surface of the seater, not just polish it.
And if THAT doesn’t work then stick the tip of each projectile into some Imperial dry neck lube before loading and it won’t stick or ring anymore.
