    Hi guys i purchased an old hw77k which needed some restoration i have now sorted the rifle out but would like to do the john bowkett tune on the hw77. But cannot find the article online anywhere so i thought i would ask on the forum if anyone has a copy of the airgun world tuning guide by bowkett himself. If so would you be so kind to pm me a link so i could download it thx guys.

    According to a post on another forum, it was published in the May 1991 edition of AGW, and basically reduced the stroke, increased piston mass and had a twin o ring piston head.
