Loss of Power Update

[Tanuki]

So I received a chronograph as a gift recently. I used it to confirm the bolt o-ring replacement helped but did not fix my loss of power issue. With the o-ring replaced I was still only pushing a .22 10 grain pellet at 760fps. Yesterday I bought all the o-rings that I though I might need and this evening I took apart my air-rifle. Turns out that a pellet had made it behind the bolt and had dropped down in front of the striker/hammer and the transfer port chamber. It was pretty well flattened but prevented the hammer from opening the valve fully. I thought that maybe I had loaded a .177 but it weighed in at 14.48gr, so it was defiantly at .22.

So here is the bolt in it's normal position:

Here is the bolt pulled fully back in order to advance the magazine:

I'm not sure what I did but I must have raised the rifle when pulling back the bolt and allowed a pellet to slide backwards and slip past the bolt was pulled back fully.
