I heard on the Cincinnati radio station this morning that the Bill Goodman gun and knife show is in Dayton this weekend. If you're close enough you might be able to pick up some powder there...but Ohio is a big state.What part of Ohio? I used to live in the NE part and I will soon live in the SW part. I was usually able to find what I needed at local gun shows. It's been a few years though so I'm not sure if that still holds true.
