CVA was only a seller of Pistols they did not manufacture them selves I would say it is a repo of a navy revolver if it is a 36 cal or a 44 cal 6 shot revolver they had a ship engraved on it. It is a functional reproduction made in the late 70's. It will shoot a .454 ball with 30 grains of black powder. It was sold as a confederate model 1850 navy.Original black powder firearms will never be marked "Black powder only", since at the time, that was the only form of gunpowder. As said, your CVA is a modern reproduction.
I would need to know the caliber and type (revolver, single shot. flintlock, percussion) to answer the question exactly, but the best place to start is with as many grains of powder as the caliber divided by half for a hand gun or revolver as a MAXIMUM LOAD. So a .45 cal. would be about 20-23 grain. I usually start out around 12-15 grains and work from there.
Kits were made by Connecticut Valley Arms Otherwise known as CVA
Between 1910 and 1930. Many (all?) of these were meant to fire blackpowder cartridges only--Modern smokeless powder may not be safe, and it will accelerate wear to the gun.
