Herter's Handles

[Whitespider]

I picked up a Herter’s single cavity mold #357173, except for the round lube groove it looks like a pretty darn good rendition of the Kieth .357 SWC. Although covered in some sort of waxy substance, the mold could pass for never used. I'm anxsiouse to try this boolit in my K38, but I have a problem.....
The mold blocks and handle slots measure the same as Lyman single cavity, but the handle pins are too large to fit through Lyman handles. Anybody know what, if any, handles work with a Herter’s mold?

Herter's moulds were made by Lyman. It sounds like your mould may have been modified after it left the factory. I would just take a drill and ream out the holes in the Lyman handles and use them (they will still work for Lyman moulds).
