TF-99 continuing story
Today, 18 formal rounds, three different pellets, three different targets. All at 25ft.
The Beeman Match Wadcutters had the best showing. The 6 rd. group about 1.25 inch tall and .5 inch wide.
The Daisy Precision Match Flat Nose, 1.75 in. tall, 1 in. wide.
The Crossman 625 Domed, 1.75 in. tall, 1 in. wide. These also shot about two inches high, and threw one stringer, about 2 inches from the rest of the group.
Moving out to 100 ft with mixed Beeman and Daisy pellets, the pattern opened up to 4 inches high and 2 in. wide, with 2 wild stringers out of 14 shots.
All shooting was done without a rest from the kneeling position. As recommended by the Compasseco Tech.. (no benchrest)
Todays conclusion: I can see the difference the match grade pellets make. But I’m still not nearly satisfied. I can also see that my technique is a part of the problem. These spring air guns are a pain to learn to shoot. Bottom line, at 100 feet, I can fire my 6 inch barreled S&W K-22 (double action), and shoot tighter groups than these!!!!! Single action, the K-22 will blow these groups out of the water! But, at least, if I watch my technique, I can keep them in the 10 ring. (better than previous shooting sessions) I suppose it’s still a “work in progress”.
