    Diana 240 Classic Keyholing

    I got my grandkids a new Diana 240 Classic in 177 and while very accurate it keyholes the pellets. My son tried a couple of different pellets with the same result. Any ideas? TC

    Need more information- distance you are shooting, type of pellet?
    I'd say I care- but I'd probably be lying...

    Brand of pellet is unknown, just some he had laying around,probably older. Distance was maybe 10yds at the most. TC

    Well, without any data on the pellets, we can only look at other possibilities- the rifle is either so underpowered it is allowing the pellets to tumble- as the 240 hasn't been made for a few years, where did you get it and are you reasonably confident it is shooting at an appropriate power level (i.e. above 400fps)? Other possibilities are that you have a burr on the barrel crown or some sort of obstruction on the front brake- i.e. hole is too small allowing pellet edge to catch, or a burr or deformation of some sort.
    I'd say I care- but I'd probably be lying...
