All arguments aside, here is my suggestion: First, there will be a bit of play when the hammer is co**d. The reason being is that the hand is attached to the trigger and needs to have some play so that when you pull the trigger, it can still move up a fraction of an inch to release the hammer. If the hand was tight against the ratchet, it would not be able to rise and jam the mechanism. Check to see if there is any play in the cylinder when you pull the trigger. Hold the trigger at its rear-most position and check the play in the cylinder at the same time. If there is still considerable play, then you may have a problem. Chances are the play will be less, or perhaps none at all. Secondly, if your bulldog does not have a rebounding hammer, it will have a "safe" position where the hammer nose is retracted far enough behind the recoil shield to allow you to rotate the cylinder with cartridges inserted. If it doesn't, there is a problem. From your pictures I am guessing it's a Belgian made "British Bulldog". Probably would not take a 44 Russian. The American made ones (Iver Johnson, Hopkins & Allen or Forehand & Wadsworth) have a long enough cylinder to accommodate a 44 Russian cartridge. You will have to find, or make 44 Webley. Don't give up on it. These are really cool little guns.
