Hi Nick
Try putting a straight edge along the left hand side of the pump tube opposite the pump arm --- the pump tubes can bend.

Git to shoot my new to me Dragon today. It shot a lovely little group at 25 yards. Three feet to the right of the POA!
A closer look shows the barrel is canted to the right, possibly by the front block on which the barrel leans heavily on the left hand side. These holes are original to the guns manufacture, but with the front block removed it is clear that the barrel wants to be well to the left of the centre.
I can probably fix by enlarging the blocks fixing holes so it can be fitted where I want the "top" to be, but I am concerned that in 24 years the problem hasn't been apparent to its original owner.
Opinions?

Completely strip the gun then find two lengths of bright round bar that are an exact fit in the pump tube.
Mount one bar in a vice and slide the tube on until it reaches the cocking arm slot, then slide the other bar into the other end of the tube and pull like buggery in the appropriate direction.

From somewhere I read that the front block uses an O ring or rings to sort of free float the barrel and centre it .
How the flipping eck do they get their pump tubes bent????
WANTED: Next weeks winning lottery numbers :-)
Imagine the pump tube and pump arm as a capital A
When you push the feet together to compress the centre bar (air), the sides of the "A" are trying to bend round the centre bar.
If the pump arm is stronger than the pump tube, then over time the tube will bend towards the pump arm during pumping.
All the best Mick

For .22 Sporters , the old schematic online shows a machined O ring recess to the barrel a few cm's back from the muzzle - where it is inserted / covered in that lumpy front block , with an O used to free float ( my words , maybe not the designers intention ) , with a specific part No .47 for this barrel O ring .
Did see that there was once online a mention of this being only for the Sporter .
What they did for the Target version , fraid no idea .
