Did it shoot fine before you rebuilt it? If so has a piece been lost or gone in a different way etc?
Have you established it is chopping pellets by shooting them into soft cloth and examining them? If so you probably know it is misaligned already. Rather than keep poking stuff down the barrel from the muzzle end which may damage the bore or crown I suggest removing the piston innards etc and with the tap closed have a good look through the action, tap and barrel. Is the bore through the tap perfectly circular or does it look impinged by being misaligned to the barrel?
Not sure if this is of help, it is the BBS equivalent of thinking out loud
I was about to make exactly the same suggestions. You might like to fire a pellet or two into a bucket of water, which should produce a clean pellet afterwards. Place a thin piece of paper over the bucket, to prevent the splash back, which could wet the barrel.
It is quite difficult to see what is down the cylinder with a torch because of the distance but it should produce a guide. It sounds to me as if a new tap has been introduced at some stage. Quite what to do to re-align tap with barrel is a complex question, to which I do not know the answer!
It is strange that two in three are sticking; you would think there would be consistency with all three.
I understand the taps were bored through as part of the barrel, so were a perfect fit in each instance.
