are RCBS handles the same as Lyman?

[robpete]

Are the four cavity handles interchangable?

[Mk42gunner]

No.

As far as I know, RCBS does not make four cavity molds, therefor no four cavity handles. The RCBS two cavity mold handles that I have are too thick for the slot in the four cavity Lyman mold.

Handles that are too thick for the slots in the blocks can be filed to a smaller thickness and corresponding holes can be drilled in them to complete the fit. If the "new thickness" of the handle tangs are then too thin for a set of blocks that needed the larger tangs a shim made out of any metal(aluminum is best because lead will not stick to it)...one shim for each side with a hole for the pin will work well. An alternative worth considering is the Lee handles which are very reasonably priced and they are easily altered to fit different sized blocks/brands. There is/are reference material and articles on the forum on this subject. Search & read. LLS
