Mark on ramrod, some use knife, I have seen tape used, I also seen paint, different colors marking different loads, IE 70 G Powder Sabot (red) 85 G Powder and Patched Round Ball Yellow. depends on barrel and the types of projectiles that can be fired and best load mark up. What the shooter chooses, I have seen the different used with In Lines More their barrels can shoot different projectiles, with their twist rates. One might find a dual on a smooth bore Shot gun Load VS a Patched Round Ball load to each his own, I do not use them, I look at my ramrods in the empty barrel when purchased, after I verify the barrel is empty. Like I said to each his own, CVA Buckhorn mag, CVA HunterBolt, CVA St. Louis Hawken, .45 Stag Horn I know where the ramrods sit on empty MY CHOICE. I also will tell folks to shut the hell up I am loading, their safety as well as mine. But alas as a result I am often shooting alone, which well is more fun than most will ever know. My dad, RIP, OFTEN more than one occasion which was not many, but a few has said "Boy if your going to be stupid you had better be tough or carry damned good insurance" but alas we was GEN X.
