Shooting today noticed my 100 yd. impacts tracking straight up in approx. 1/2" increments. Pulled covers and noticed after each shot the turret was moving by its self. Have never seen this before. This is new bbl. 24" ss bull bbl Thompsom encore, 6-24-50 scope with weaver mounts, all tight. Only thing different have worked up load to 24 gr. of acurate 2200 powder pushing 55 gr.fmj from23.5 and .007 freebore jump. Up until today haven't had this problem. Could it be that this load is starting to cause bbl to vibrate and twist the turret mtrl. And cause it to move? Also the astmuth turret will move but not as much, or am I way off base?
