I recently got a CZ200 and the bolt was super sticky. Turns out the screw that interfaces between the bolt and the cocking lever was bent (but I can imagine the same thing happening with the equivalent screw that interfaces the cocking lever and hammer). Replacing that made a world of difference

This is great information! Thank you

Thanks for the support! I think I would be very proud if someone thought this was a good enough idea to steal, so I will make it easy for them... I would be interested how they did this in the 1940s. I ended up using a PLL and that seems pretty high tech for the 40s Basically it works by...

I wanted a chronograph, but didn't want to pay for one so made one. Currently it's very prototype-y but if others would be interested in building one I'd be happy to polish the design a bit more. Currently just capturing the waveforms with my ocilloscope, and the detectors are giving high SNR...

this one sold already?

I wonder what causes the difference in energy. Maybe on some p17s the seal between the barrel and the air chamber leaks a little. or maybe something to do with the gap between the end of the piston and the end of the air cylinder when the gun is closed. smaller gap --> higher pressure --> more...

sorry for being too confident for my understanding. Thanks for sharing. i will explore this piston bounce thing further.
