I set up these two saline nasal spray bottles at 102 yards. Shooting off my deck, bipod and rear bag. Bantam Sniper HR sending JSB Exact Jumbo 18s. I asked my wife to guess how many shots for a hit. She said two each. Two first round hits later and it was on. I walked out there five times. I laid one of the bottle on end and still got my hits. Lots of walking but fun.
