What causes Keyholing in shooting?

Keyholing is a sign that the bullets are not being stabilized properly. If a gun shoots maybe one keyhole in 500 shots, it may just be due to a bad bullet, but if it regularly shoots keyholes, then that means there is a problem with the barrel or bullets or both, which needs to be fixed.

Drag is also influenced by bullet spin. The faster the spin, the less likely a bullet will “yaw” or turn sideways and tumble in its flight path through the air.
