Somewhere / somehow I have developed a "push" and a trigger jerk. 15 yds with decent 3" groups but all at 8 o'clock and about 4" off center.
After 50 rounds or so I was starting to return to "normal" with 3" groups at 9 o'clock about 3" - 4" left of center consistently. I decided to quit while I was ahead instead of wasting my time and money.
Maybe it was just the day. Maybe it was the ammo. I sure hope it was something besides me....
