We fashened a 55 gal. lid to a tree 1000 meters away. (Remember, we were artillery surveyors) We loaded a belt of only tracers, and from where I aimed the lid looked liked a period at the end of a sentance! We used a spoter with binoculars to adjust our fire, but sense it was a free fire zone we never, personally, checked our accurecy!
Thanx Dante'
