just fired one chamber--i used a 22 to 25gr powder flask and i think i filled it 2+ maybe close to 50 to 60 grains the ball seated fairly deep in the chamber so I didn't fear too much of an overload-- no wad was used or over ball seal--but i do remember when we got these balls, they were a little different and would not seat in army or rem 44's They appeared to be lead but were hard. Had round top stamped on them? so i tried in the dragoon and it snugged in--maybe a 454 maybe not - when ordered they were for 44's but like I said you could not ram one in a colt or rem 44 so they were put away. After examining this colt dragoon , I thought one might fit in' this' since it was a bigger gun. It did but I was a little leary but damn if didn't blow out like a rat eating cheese
