I hollow pointed a Lyman SC .458 boolit mold and I sweated the outcome, from now on I will stick with Lee molds for hollow pointing and Rangefinder’s method looks pretty slick. The way I did it was simple and Hollowpoint has also done it using the same method. I was a little concerned after casting a few up, for the hollow point holes indicated 0.02” to 0.04” runout, but the boolits worked out good and the .45-70 accuracy did not suffer at all.
I had to make a different pin, as the first one was short and I had a wooden knob on it, had cast very few boolit when the wood started smoking and charring. (that big cast iron mold does get hot) So made up a longer pin and took Leftiye’s advice to forget the wood and manipulate the pin with pliers (small pair of vice grips)
In pic, the boolit on the left is the one I used as a pilot to drill the mold,
