Had a small group of special police officers out for revolver qualification. Local USMC reserve unit kindly had agreed to let us use their indoor range.
The senior NCO had quetly advised me that the Instructor/Inspector (active duty Marine Officer) might drop in while we were shooting- and by all means, ask him if he would like to shoot- but under NO circumstances make bets with him.
Sure enough, the I/I dropped by. Displayed some interest in the revolvers we were using (S&W Mdl 65s) . Asked if he would like to shoot a couple of the timed event rounds- fire 6, reload, fire 6, 30 second limit.
He proceeded, with a borrowed revolver, to shoot the X ring out of the target- 12 rounds, double action- in well under 30 seconds. Found out later his prior assignment had been on the USMC pistol team!
