This shock wave can do several things. 1 change bc unexpectantly with varying effect for atmospherics, 2 change the trajectory of bullet flight and 3 cause the bullet to loose stability.
Why does slowing the twist or just adding a few thou to the jacket ,with no exterior design change, help if this is what was happening?
