My .177 loves Crosman Premier hollow point pellets. I have tried nearly every other type and this one is definitely the most accurate in this gun. These pellets are filthy with black residue (is it lead or carbon/graphite?). More importantly, there are metallic slivers and some remain even after I batch clean by dumping pellets on clean rags and applying isoprpyl alcohol. Pellets are then repeatedly wiped with more clean rags/paper towels. In the end some slivers remain, preventing more groups of <0.5" at 57 yards. I am considering buying an ultrasonic cleaner.
Any suggestions on getting these impressive pellets free of metallic debris?
