Excellent! A dozen years ago I took an HBAR out to the desert in wyoming and with a little practice and some Kentucky windage was able to plink at large rocks/boulders 800 to 1000 yards away. Thanks for the link...I especially like where he said to think marksmanship and dont always try to get 15 rounds in a target 15 yards away in 1/2 second. Everybody I work with is into spray and pray and derides me for trying long range carefully thought out shots. This was refreshing to read.
I didnt intend to imply the violent action of 15 rounds in 15 seconds is not useful. But it has its place along with the more "traditional" marksmanship.
I also fired the M4 carbine to 1,000 yards if you are interested in the results from that
