.177 - try heavier pellets
If you're getting over 950 fps or so then you're pushing the speed of sound - and that does nasty things to the accuracy. Heavier pellets will slow it down a bit. ALSO, pellet guns tend to be very picky as to which pellet they like - or don't like. Drop by http://www.pyramidair.com and pick up 4 tins of various pellets, or more. Try different brands - and make sure you've got a clean barrel. At Pyramid, every fourth tin is free, always the cheapest tin of course.
