Dr. you will have time to sight in your gun.don'y worry.didn't see you last night at the range.anyway good luck .BTW i don't know what gun or cal your shooting , but it don't matter with the AGBR target -.177 or .22 cal @ 25 yds just couldn't be easier any way hope that you can make it, i just don't under stand why the group shooters are so intimidated by this target @ 25 yds...and there shooting at 50 yds ....? no one was ever told that they coudn't shoot the AGBR with a .22 cal at our range and Charline " the one that runs the matches " has bent over backward to try and accommodate every one .but if you think you won't have fun stay home.H.B.
