As somebody else here said, the first thing to do is clean the gun. You probably got something cleared out from between the hand and the spring and it is now working easier because of that, or in the hand slot, either way, no harm, no foul.
The hand spring on most guns though, is the easiest to break, and it can be done without any real trying. Best, when reinserting, to have some lube on it.
Also, when you shoot, expect about 12-18 shots before you have a hard time rotating the cylinder because of black powder residue fouling. Don't worry, you will see it. Looks like a thin layer of soot, which is basically, what it is. Warm water will take care of that, but dry off the gun before trying to reload again as water and black powder do not mix.
Also, get something ahead of the bullet to lube the way, like Bore Butter or Crisco Shortening. It helps to soften the fouling and you might get 18-24 hots before really having to clean again. But that is the 'fun' of B-P. Also once the wedge has been moved a few times, it gets looser. No need to really whap it back in all the way until the barrel touches the cylinder, too. There is supposed to be a small gap between the two, as in a regular modern revolver. Finger pressure on the wedge will be enough to hold the barrel in place.
The Doc is out now.
PS, wait'll you start molding your own round balls. Then you will be hooked, lined and sinkered!
