Tim, I had mine before the advent of Trail Boss, and I didn't know of any other powders like that. I commend you for being able to handle a 45-120. They are the ultimate, IMO. Matthew Quigley's was a 110, I think, fired with a full load of blackpowder. If he had been a real person instead of a tv character, he would have been a man to be respected. As you are.
