Things I liked:I am shooting these from a Tech Force Contender Model 89 and they consistantly land in tight groups. I'll be buying more when I shoot these up. My yard allows for a 30 yard max target distance. I aim dead on at 20 yards and at 30 yards and usually land in or nick the red dot in the center of the target. Things I would have changed:Nothing comes to mind. What others should know:Nothing comes to mind.
