Years ago I read VM's booklet and jug choked a MLing trap gun I made. It works very well. I just did a 1894 Remington and it also patterns just the way I want. For those of you who don't know about Mr. Starr, he won many shoots against modern guns with his muzzle loader. They would shoot at a playing card and see who could get the most BB holes in it. Many times competitors wouldn't shoot if he was in the game that day. Now a days it's quicker and a whole lot easier to put in replaceable chokes. It would be nice if a certain Dr. would refrain from commenting if he doesn't know what he's talking about. Maybe you don't know everything and could possible learn something here. Paul
