I'm using range lead at approximately 8.0 BHN. When I seat a 457124, which is a round nose, I get a ring from where the stem doesn't fit the nose profile. The die is a Redding.
Anyone know where I can get a seater stem with the correct profile?
or
What is the best way to make one using epoxy including release agent for epoxy and how to keep the epoxy from glueing the stem to the inside of the die when trying to make the profile with epoxy in the stem, inside the seater to form the profile?
Thanks!
