I have 3 rifles and 3 pistols. 2 .45 cal and one 50 cal rifle. I always in the past used 3f powder in everything. I have been thinking of getting a .54 cal rifle. Can I still use 3f or should I go to 2f and what would be the advantages and disadvantages? Sorry if this has been discussed repeatedly but I searched and couldn't find anything with the search function.
