BC, you just apply light pressure with your finger against the cylinder when you cock it so that momentum won't keep the cylinder rotating. If it is out of time the cylinder stop won't pop into its recess on the cylinder.
If it is only slightly out of time it isn't going to cause any problems. It the bullets are impacting the side fo the barrel then you should be seeing evidence of lead splattering or an excessive ammount of copper build up where the bullet is impacting.
If the one cylinder is definetly larger than the others then this is most likely your problem. No real way to fix it that I know of other than purchasing a new cylinder. You can't make them smaller.
wow!! this thread has been a major help!!! great trick there to check cyclinder lock up timing. I tryed it and consistantly that bad chamber was off time, my earlier thought that maybe my chamber was out of size with the other cylinders was totally wrong I checked all my cylinders for dimension the rear of the chambers all measured .380 dia. and the front end of each chamber measured .358 dia. My conclusion is the bad chamber is deffinately due to lock up timing. I closely examined the recess on the bad cylinder, guess what?? theres grime and dirt build up in the recess that went totally unnoticed.... All I have left to do is try firing it and see what kind of results I get.
wish me luck!!
