Re: Teaching an old dog new tricks
The CVA is probably a 1:48 twist which will work well with lead conicals or patched round balls but isn't ideal for either. Black powder is best. Loose Pyrodex is second best(IMHO). Powder charge will depend on projectile used and the guns performance but will most likely be in the 90 grain range. Powder is measured by volume not by weight, this is very important where the subs are concerned as they all weigh less than real bp. Cleaning is with hot soapy water and vegetable based oils, not gun oil. BP fouling is not affected by smokeless cleaners but dissolves in water. Caps will be #11, I prefer CCI. The CVA has a drum breech where most sidelocks use a snail breech, so magnum caps might work a little better with subs. Always load a rifle from a powder measure. Never load from a flask even if it has the proper size nozzle for your powder charge. All it takes is one hot ember to turn a flask into a grenade. If you use conicals you will need a short starter as they are usually difficult to start.
