Forty / 10mm is the only caliber I have shot for a long time but had not cast for over the years.
Not long ago I bought the two styles (2 SWC and 1 TC) of the Lee .40 cal 6 cavity molds. After extensive load testing, functionally in all of my .40 handguns from Beretta, S&W, 1911 and Tanfoglio they perform (no chronographing yet) identically. I've powder coated and loaded very close (depending on which published data I read) to the Accurate #5 max loads for FMJ and have not had a single feed, eject/extract, accuracy or pressure issue in four, five, or six inch barrel lengths. Add to that in terms of sheer production they beat the tar out of my many four cavity molds from Lyman, so I'm a very happy camper. So I wish they made the 401-145 in a 6 cavity version to try, I will not go back to a 2 or 4 cavity style.
Does anyone know of another maker who offers a custom or OTC 130-145 grain SWC or TC mold in 5, 6 (or more) cavity?
