Bats have radar that help them dodge the shots

Bat sonar is 100% useless at avoiding incoming supersonic projectiles. They could learn to dodge when a gun barrel points in their direction. Probably it just means that they tend to make sudden sharp changes of direction.

Aren't most shotgun rounds barely supersonic at the muzzle (1100-1200 fps)? By the time the shot has travelled a few yards, it may no longer be supersonic.
