Can anyone give me help on selecting a good load for reloading the sabot shotgun slug in45 and 50 caliber. I want the high velocity, like Rem core lokt, not the copper solid. Which powder would give the best performance? I don't want to have to buy a dozen different powders to try out. I have reloaded shot, but not slugs. I do have a little knowledge but still need help. I will appreciate any help anyone can give me.
