Oh I see, yes I’ve seen his video. I would not recommend using 22 primers. They are far more potent and could potentially weaken your mainspring with the blow back. When fired, your hammer is pushed backwards. I’m no expert but my opinion is that over time it may put stress on it and cause problems. As well folks say never use smokeless powders in a BP revolver due to the high pressure tolerances, I’m not sure if that would also apply to primers. The cap tool from .22 Sharpshooter is pretty easy to use and more economical I would think than purchasing .22 primers. I would be interested to see your solution to the height problem though.
