[quote=tw))1) rotational or centrifugal force has a significant effect on target breakage. I happen to subscribe to the idea that a single pellet strike can cause a target break, not all the time, but frequently when the targets are good quality pitch & the machines in good repair. tw, Dr. J's research agrees with your observation. He tested with realistic rotational speeds but no forward airspeed. The major mode of failure with a single pellet hit was for a fracture to radiate from the strike and cause the target to separate into 2/3/4 pieces. Were the fracture not subjected to the continuing centrifugal force of rotation it is much less likely to separate.
