It was hot outside, and the shop in the basement was cool, so I broke out the dial indicator and warmed up the Bridgeport to take a crack at converting a Lyman 356402 mold to hollow point format. Why??? Well, just to be different I guess.
The setup when much quicker than I thought it would. Just lucky I guess. I center drilled the hole to start, then drilled the hole first with #38 drill, then followed up with a new 1/8" bit. The hard part was done.
I then used a piece of 1/8" 303 to machine the pin from, as it provided a nice fit to the hole that was drilled in the cavity.
A bit later, I needed to cast some 6.5mm bullets so I decided to see how the modified mold functioned. 10:1 allow isn't optimum for HP bullets, but what the heck. If they shoot as well as they look, I have a winner.
