Bought some Hornaday .375 muzzle loader balls today and poked them thru a .358 sizing die. They fit nice in a belled .38 Special case. I'm thinking about 1.0 grain of powder of some sort.
Anyone play with this setup and how light of a load and what powder did you use? I'd already know the answer to this but it's not wise to fire said load in my neighborhood. I elected with "wise" and didn't test things.
