Matching Seater Stems?

Welcome to the forum!

If we could come up with a “one size fits all” type thing I think we could do it
Just to many types of seaters out there

How about a program to send your die in? I bought your 311 247 mold with the HP cavity and the HP noses swage slightly in my seater causing them to seat shallower than the FP boolits. I dislike having to reset my dies.

Buy another seating die.  It’ll be cheaper than postage plus a custom seater from a bullet mold company, for your existing die.
Or… have the die maker make a custom seating stem for your die or a new seating die.  Pretty much all of them offer the service.  Most have reasonable prices and very quick turnaround times.
