The 215 is a cut down LEE mould I made for stepping up the .375 Win. and .375 GNR. I loaded 50.0 gr. 4895 and they shot great, I think around 2100 fps? Still lower pressure.
The 300’s are a little crazy but look cool. In my backstop I noted they tumbled and riveted. I found one in the shape of an “L”. I always figured I could entice straight penetration by filing a flat meplat on their noses. Plenty of weight to work with.
Have you worked with the traditional .375 255/265 gr. FN for the old .38-55 Win.?
What velocity are you running? The powder? Wondering the burn rate range.
