l own a Daystate Revere and an AirArms S410 both .177 both accurate rifles but recently l noticed the S410 seemed to be dropping off in accuracy and not because of a drop in pressure so l cleaned the barrel with a pull through and was pleased to find that it was back on the mark, so my question is are any brand of pellet any cleaner than the rest ie are any brands fouling the barrel with fewer pellets fired through the rifle than any other brand.
Is it down to the quality of the lead?
