I used it a few months ago to try it, in 38/ 158gr, was ok but went to Gm3, now using Vit n310.
vectan doesn't like being reduced, I decided I was going to stick with .357 in my marlin

Answer to your question yes can be done .38 big bang. Need to reduce bang for paper target shooting.

If I was going to shoot big bear and there was nothing else would use it.
