I want to get a mould and cast a good bullet for hunting in Grizzly country. I am looking for something between 400-500 grains that I can load for my .45-70 Marlin 1895 SBL. I want something with a wide meplat that can be driven fast enough to crush said Grizzlies. As I'm new to casting and the .45-70, what do you recommend for a mould, and do I still need to size and gas check etc. Any help is greatly appreciated
