But, a couple of thoughts:-

Firstly, as mentioned, some often say that Crosman barrel crowning can be very variable.

Secondly, I'm wondering if the barrel is "fixed" at the breech end with the flimsy grub screw arrangement, as per the 766/2100 rifles and whether this has worked loose?
It's a reet weird contraption with the 'straw' barrel cast inside a plastic liner. It was made to look like the Winchester Model 70 so it is the full 'Hemingway' but it shoots shite.

I will try the pushing the pellet through idea, nice one. Might not be able to get to the crown as it is recessed.
