I mis the crosshairs when using a red dot I find I use them to determine point of impact as much as the center +.
I have had an aim point and another red dot but could not group at long range for me that is 100 to 300 yards as I can with even a 21/2 power scope . I read about guys doing very well but not my experience .
Rifles I have had that I can shoot at less than an inch at a 100 go to 4 to 6" with a red dot . I have just mounted a Burris fast fire on a 10-22 to play with and will be a short range toy will see how it goes.
