Lyman 310 cartridge adapter thread size

[Char-Gar]

Does anybody know the thread size of the cartridge adapters that screw into the 310 alloy handles?

Never mind, it is the same size as the die threads. I am a little slow this morning.

yes, same size, .605x30 --
they are a bit of bother to make -- with only three threads, you have to be quick :-)
