The owner's manual says to use "Super Pells," which are no longer available and from what I hear were pretty crappy anyway. I've been shooting 14.3 gr Crosman Premiers with decent accuracy but with an occasional jam. Are domed pellets best in this pistol, or should I be looking at wadcutters? And what about lubing the pellets before loading into the gun? Any experience-based advice about this would be much appreciated. Thanks in advance!
