If you have to use a shotgun to hunt flying food, today’s invention might help. This consists of a shotgun with barrels which move independently.
If a gamebird is being tracked from the hunter’s right to left, an accelerometer in the butt senses this and drops the left barrel by a fixed amount.
The right barrel is fired first and automatically followed milliseconds later by the left one. This allows the recoil from the right to raise the left one to be more nearly on target, optimising the placing of shot around an unfortunate bird.
If the bird is flying left to right, the sequence is automatically reversed.
