I don't shoot a inline but have helped a lot of people work up loads for them and every one that I have worked with has shot better with measured powder charges of cannister powder. Take your choice of brands they will all work just may have to work with the load abit. Most of the time charges around 100 grains by volume work best, and for best accuracy at 100 yards benchrest really requires wiping the bore between shots, contrary to what the made for TV info garbage says. Good luck and keep your powder dry, hope to see some dead deer soon.
