When I got into casting a few years ago I bought a box ful of assorted items. Among them were 4 single cavity Lyman/ideal si gel cavity molds. Three i use and really like other then they are single cavity. The fourth is a single cavity 429184 that is a hollow point mold with no pins. Based on my research it looks like it was a round nose design for the Russian and special. I would like to use it but never have messed with a hollow point mold. I don’t want to take it to shop and take the welder or torch to it. Not sure what to do with it. Maybe make a pin for a flat point design?? Would be used in 44 mag pistol. Any advice would be appreciated.
