They work..But I don't recommend using them unless you consistantly shooting at targets or game animals over 350yrds...If its just the odd time, those reticles can really screw one over,(lets face it, those crosshairs are close together)ifa hunter/shooter happens to take a shot an animal,especiallywhen shooting 150yrds and under..
I've seen it3 times in as many yearshunters will put the wrong crosshair on the animal and its missed, or wounded
one (moose)was not recovered.
