This happened last Saturday at MDR: A "buckerette" attempted to engage a rifle knockdown target, but jacked out the round. Any of the remaining rifle or pistol knockdowns could have been cleaned up with the shotgun. She left the rifle target up and did not try to knock it down with a shotgun round.
The TO and the spotters reasoned that, because buckeroos/buckerettes are not required to knock down knock down targets, only engage them, she was given a call of "clean". Was this a correct call?
