I'm not sure I have the skills for condition butterscotch. I use an 18# recoil spring in my 1911, so I pretty much need to use a bushing wrench. Now tools are involved. I'm thinking cocked and locked is the one for me.
Flintlocks, as well as any 'hammer gun', that is to say a gun with an exposed hammer such as all the lever action Winchesters and Marlins and single action revolvers have a sear (notch) in the hammer which holds the hammer at 'half cock'. This is the 'safty'. If this sear is worn or defective the gun can go off unexpectedly, or "go off half cocked".
I don't think it's a good idea. Something will go wrong.
