It has werqed for pellets out to 100 yards so far. I push the button and it automatically moves the reticle to that range for me. I went back and forth from about 20 yards to a 100 several times it seems to be very close. I haven't used it much yet so still learning so have as yet not got the settings for the pellet bc, speed ect. perfect so things will match up exactly but I am pretty close within an inch at 100 yards. I had to shim the guns scope mount by 20moa to get enough elevation for things to werq properly.
