I was playing with the softChrono program a bit and am trying to sort the data.
With the microphone at the breech, Three significant events are recorded.
The first is short and crisp (metalic?) I assume the striker impact on the valve pin and stop block. 0200
The second follows after 100+ ms,The gas release?
Then there is a third event (bounce) after an additional 40 ms.
My limited testing did not confirm the exact reproduction of acoustic events, but indicative.
Question: Does a 100ms "lock time" seem right for a QB with no mods (on CO2 in summer, at low tide....
I will dry fire when the carts expire and record the signature of only the mechanical events, separate from any pneumatics.
That should give an additional look at events.
For some perspective, it's easy to tap your finger twice in 1/10th second.
The lock time from trigger break to pellet exit in a gun like the QB is probably between 6 and 9 milliseconds, with most of it consisting of the ~4 or 5ms the hammer takes to accelerate through its stroke.
