Im not shooting atm i sold my rifles because of MH prob a while back wish i hadnt because i would like to go out in the field again but i will be shortly in the market for a airrifle but unfortunately wont have anywhere to use it as gave it all up back then just have to keep plodding along
as for your pellets that stray a little might be down to the weight of the pellets get urself some pellet scales off ebay £10 or so to weigh the pellets in the tin once u get urself 10 pellets of the same weight try those at a target all in the prep work for better shooting thanks for your reply
