We spent some time tonight calibrating our shooter, and I have to say... we're all pretty happy with the results! We made it without touching top or bottom from less than 5ft away from the wall, all the way out to almost 20 ft away!
This is our max distance shot, about 20 ft away

Oh, and we're as close to 100% consistent as you can get - 4 shots in a row from the same location went right in the same spot!
