Not sure what type of bullets those are , are they hard cast ? I only use pure lead bullets , round balls mostly . Can't remember all the reasons but if hard cast they are mostly considered a no , no . More leading , pressure ect . And yes round balls are way more accurate then conicals . Most shooters at those shooting events use them for that reason . Conicals were used and most paper cartridge bullets used them . The ones they were issued or could be bought at the store . You can buy conicals made for BP at many places . You wouldn't have to worry but the loading levers on revolvers are made for round balls and when trying to load a conical if the loader isn't modified or changed they will deform the conical when ramming it into the cylinder . Or at least with lead bullets . Also Dragoon ???? Mnnnnn I like Dragoons . You may need to start another thread !!!!
