    Remember that the tap can be misaligned laterally or vertically. If misaligned vertically, it indicates that the tap is either being closed too much, or not enough. I put a score into the inside of the pellet skirt and check it's position in the tap before closing and firing. The recovered pellet can then be examined to see where it is being chopped, left or right, or top or bottom.

    Lakey might have a view on this; he knows these rifles well. It certainly sounds as if it is the tap but, if so, what is the solution, I wonder.

    Working now

    The tap has worn and is traveling too far to the right,After removing the ball but leaving in the spring (which is just touching the cover plate)she’s shooting every shot,if I overtighten the screw on the tap side it pulls back the tap body and chops them again,if I make a shim that sits on the end of the tap so it lets the screw Not tighten down the tap body but leaves it tight it should leave the body in position and not pull the tap body over.
    Otherwise I would be looking at a new tap body for£55 which is never going to happen lol.
    Plus I would have to bed in the tap body again and for what I’m going to be using it for it’s not worth it (spinning cans).

    Interesting; it seems you have cracked it.

    However, the tolerances on these fittings are very fine. Whilst the rifle is now firing, is it firing accurately and producing groups? Or is the pellet still slightly veering to one side on entry? It is strange that the tap has become worn and I was unaware that by tightening, the tap could be moved. That in turn suggests care must be taken when tightening the tap screw but what is the reference point by which to determine the tightness?!

    I don't know how the pellet moves/jumps, in travel, from the tap to the barrel. Thus, is the start of the barrel rather larger and does it then taper inwards, so as to guide the pellet during its flight? Certainly, the tap itself is very slightly tapered inwards at the bottom.

    Is it a tapered tap or not?
    /In case of Osprey ST: Dunno when they started making the ST but iirc early Ospreys didnt have tapered taps giving problems with pellets.
    Webley fixed this by fitting a tapered tap.
    In case of tapered tap; make sure its on the right way around. It can be fitted either way.
    The wrong way and the pellet will stick out on top (wont fall deep enough)

    Edit: see you fixed the problem. Nice work
    ATB,
