Ever read about the "mad minute?" Brit troops were trained, during ww1 at least, to fire several aimed shots within 1 minute. I dont recall how many but it was very impressive. One story goes that a group of Germans were being fired upon so fast by Brit troops with smle's that they thought the Brits were using machine guns. I recall they would grasp the bolt knob with the thumb and forefinger, work the bolt, pick up a target as they closed the bolt and fire with the middle finger as the bolt was slapped closed, without taking the thumb & forefinger from the bolt knob. Lather,rinse,repeat till the rifle ran dry. I have tried it with an empty gun and it seems possible. Do us up a vid doing the "mad minute" drill. This guy does a fair job at 1:50.
