I think I tried just about every thing even a special breech plug and musket caps still had that awful crud ring and blow by; went to APP and got tighter groups by far the capability of using mag loads and still keeping the tight groups and the capability of a second or third shot with out cleaning and in the group all the time. It may not work the same for every one but that is all that goes into my inlines now; I like real black powderfor my Hawkens.Lee
