thanks for that bud,i use superdome pellets which seem to work well with my rifle,thinking of getting hw100 which my freind has,i tried his last time we was shooting together,his is a lot quiter than mine and when we had abit of target practice on a steel tube that was sticking up out of the ground about 30 yards away with his i hit it every time,with mine i missed a couple of times,his gun was alot more money than mine so maybe better on quality.
