Dragged a few patches through the barrel and shot today with just a light breeze. Shot 3/4″ group at 55 yards, so getting better. Will do a more through cleaning job and test again. When group sizes stop improving at 55 yards will start working on 100 yards shoots.

Did shoot a bunch of Crosman Premier Hollow Point 14.3 gr. Although not as repeatable as the JSB 15.89 gr they were pretty close. Pretty close equals 1.25″ (9 shots and dropping 2 fliers), compared to JSB’s at 0.75″ (no filers)  all at 55 yards and under the same conditions. The two pellet’s group centers of impact were windage and elevation equal, which was not expected.
