In general, you can never count on an excellent load for one man's rifle performing as well in another, but in my life I have encountered a few that seem to lean that way. I may have found another.
In talking to three different 308 shooters about the up-coming load development for my AR10 autoloading rifle, I was mildly surprised to learn the all three of them, from different areas of the country, related the exact same load for 308 match shooting: A good 165-168 grain bullet over 41 grains of IMR 4895, loaded to fit the magazine. One of these fellows, down in the southwest, said that one of the top NRA High Power 600yard shooters he knows uses this exact same load when he is testing a new barrel. If it won't shoot well with this load the barrel is rejected. A local shooter I know loads only this one load for all 7 of his various .308 caliber rifles.
I just thought this was interesting.~Muir
