Overall length of loads will be determined by what gives you best performance with your barrel. 2.95 inches is the max. Reduce powder charge by 5% to start. XX gr. of powder is the max, more will cause an increase in OAL as the hull fills with powder.  Special Care should be taken here. Caution: A slug fully engaged in the rifling will stick in the throat when extracting a live round!
