I went to the range today without the kids to experiment a little. The kids are just to impatient. Anyway, I shot really well with it.
I used the cross-hair for 25 & 50 yds. 25 was spot on. 50 yds grouping was about 1/2" higher, still in the x. AT 75 yds I used the next dot from the cross-hair down. It grouped out of the x circle still in the bulls-eye. At 100 yds. I used the second dot and I shot about 1/3 of bullets top bulls-eye 2/3 out in the 9-8 ring.
I think there is a little more room for adjusting. Tomorrow I am going to check 7, 10 15 yds. before making any adjustments.
Any advice for a rookie?
