Sorry for the misunderstanding Daryl but the the 1900 fps was for a single ball. I was just trying to point out that the 1-28" twist can be used for a single round ball at high velocity, at least in this gun but o have heard of several people having success. I do understand your concern with the ball climbing back up the tube. On that I think I will machine up a new brass ramrod with a permanent ring at the proper loaded depth.
