This chipmunk was taken at 42 yards with my .22, Air Arms TX200, using the H&N Baracuda Green 12.65 grain pellets. He was facing me when I squeezed the trigger, the noise of the shot caused him to cock his head just before the pellet hit. The pellet entered on the right side behind the shoulder and exited through the abdomen on the left side. I’m used to seeing 100% penetration at shorter distances but at 40 yards the pellet passed right through the length of this critter. (40yds, 769fps, 16.6ft/lbs. at target)
