Haven't personally tried them but have read on other boards of guys that are using them for shotgun. Say they load just about the same as the powders they "copied" but do not have the color markers in them like the original "dot"s. It goes without saying, relative volume does not equal weight so for shotgun reloading your bushings will probably need to be changed to throw the correct weight. If i wasn't sitting on a new jug of Titewad I'd give them a try but don't see the need to pony up the money right now.
