You yougsters that grew up on the .308 and knew that with the right scope and dope that you could shoot 1000 yards with relative hits. With the intro of the newer technology that shows down range windage, baro elevation, pressure elevation, range to, (KESTREL) and all the other goodies that assist you in hitting the target. I still get two rules of thumb to work for my long shots: muzzle veloicity and weight of projectile. And God bless the new technologies that allow you you to put this on your shoulder. When we used to shoot the M2 spotting rifle as a sniper rifle, we were behind our lines mounted on a mule that carried a 106. Otherwise, we took our M40 into the weeds and did the dirty deeds. Now, you have 50 cals that are actually made to reach out and touch at 1000 yards or more and move after the shot without motorized assistance. But, we still knew back then that it was a good system that could be developed. As there is alot of talk today about the the 300 mag. We did that back in 1975 too. In 1975 with the blessing of Col. Reynolds, we took the Weatherby 300 Mag back to the 1000 at Quantico and tested it for the next sniper rifle. Yes, Hathcock was there. He reccomended it to begin with. He understood thye benifits of higher muzzle velocity for longer shots. I worked o0n this for two weeks with the boys and then got shipped off to the drill field. Parris Island here I come. Little did I know what I would miss.
