Hey guys, thank you for all the great information. I am looking ONLY for technical advice - please feel free to start a different thread on the legal issues.

Scooter - thank you for the detailed data on your experiences. I've seen several other threads where you discuss these details and I've got a bunch book marked as I begin to learn about the guts of my revolvers. I was especially surprised to see a reference to accuracy degradation with springs that are too light. I guess that is due to inconsistent quality of primer ignition - right? I never thought of that...

Someone here mentioned the "balance" between rebound and main springs. My only technical reference, the Kuhnhausen manual, does not use this terminology. Is there a certain measurable metric to determine "balance", or is this a reference to making sure the gun works and feels as it should?
