>Bad Flynch, Where did you get the stiffer springs? Mec has a chapter in his book that shows where to grind the frame to give more clearance for the cap pieces to fall out. I like your method better which if I read you right, increase the hammer pressure to decrease hammer bounce and capturing the spent cap.<
Well, I bought new springs from Cimarron for one and a buddy simply put a spacer between the spring and the strain screw. Both methods worked fine. The other guys have not fixed theirs, yet anyway.
There is a clearance cut in the frame already. It is a semicircular groove that makes it easier for cap crap to rotate with the cylinder. However, that does nothing to stop the blowback problem. You are right about the hammer bounce, 100%.
Hope that helps.
