I have been experimenting with cast boolits in a couple of single shot rifles. The one I have been giving most attention to is a Henry single shot in .357 MAX. But I also have a single shot Ruger #3 that started out as a .45-70. I had it rebarreled to .375 JDJ. It is impressive with J-word boolits but it kicks this old man too hard. So I decided to try cast boolits in it. The first mould I got was a Lee 250 grain flat point gas check. I have loaded up some of them with different powders with good results. My original goal was to reach something like 2,000 fps with this boolit. After studying load data and reported results for the .38-55 and the .375 Winchester I have decided that my goal should be reduced. New goal is to be in the neighborhood of 1,500 fps. Better for the shoulder and entirely enough for lower 48 game animals.
Since starting with the Lee boolit I found an RCBS two cavity mould that throws a flat point gas checked boolit to about 250 grains. So now I need to cast up some boolits and try them. I have a pretty good selection of powders.
Does anyone here have a recommendation regarding powder, amount, or which boolit they think will do better? With the old criteria I was casting the Lee boolit with Lyman #2 alloy because I thought 2,000 fps required it. I am using Carnauba red lube. Since I cut back velocity maybe I'd be as well off with a COWW alloy. I have yet to see a sign of leading.
Thoughts, anyone?
