Who told you it took black powder loads?
Most were in 38 S&W which is not 38 special
You can buy Remington ,Winchester ammo at most gunshops
It, like 44-40, 45-70 and other old gun cartridges are down loaded so you don't blow up the old guns.
As long as the cylinder locks up tight and the cylinder and bore line up it should be good to go.
I've got a few old top breaks and I would not be afraid to fire any of them.
