ca.1965 - Shoeburyness, 26 Medium Regiment (RA). Our rifle team from RAF Croughton were invited down to shoot. We were using the M-16. On one course of fire, we zeroed in our weapons then backed up a considerable distance. As I recall, the drill was to adjust sights then run forward, drop into a prone position and open fire. ADDED: That sighting doesn't read right. All went well until dropping into prone, when one of our men tripped, did a somersault, sort of recovered and fired a short burst. He'd involuntarily flicked the lever from safe, past fire, to auto. It cost points, but everyone was impressed with the way he handled it ============== And that brings to mind your falling plate targets. We hadn't experience these before. The host team went first, and it all look straight forward. We were using M-1 Garands for this event. God alone know where those came from since they hadn't been a standard in the inventory "forever." Plates set up for us and on the command "fire" we opened up. What's this? Every now and again a plate would fall over but far too few for the number of rounds we were firing. The Range Office called "cease fire" and we went forward to discover many of the plate still standing had very neat and shiny .30" holes through them. I had notice the ammo we were given - again from an unknown source - had black tipped bullets - AP ball! ================ We were allowed to fire both the Bren and Stirling by our hosts. I have drooled at the sight of a Bren ever since.
