KAL bullet mold ?

[R-71]

Anyone know what size allen wrench is needed to adjust the set screw on the bullet length adjustment?

Thanks!

Took the mold to the hardware store, 1/16th". I bought a couple.

I have two of his moulds and I can't tell you what size it is but https://www.homedepot.com/p/Husky-SAE-Metric-Long-Arm-Hex-Key-Set-26-Piece-HLAHKSM26PC/202934869?MERCH=REC-_-PIPHorizontal2_rr-_-205539269-_-202934869-_-N one of these will fit it. It's good to have a set on hand.
