Checked the article your link went to and the following part of it got my attention:
"They ... provide better trajectory performance for both wind and drop than the standard 190gr SMK load in .300 Winchester Magnum,...” (then later) “Once you're using the same high-BC bullet, adding 150 fps to get 2970 fps instead of a more sedate 2820 fps only gains about four inches of wind drift per 10 mph cross!”
Wrong; a 190 SMK leaving a .300 Win. Mag drops about 10% less than the best of those mentioned in the article and much less than those using less powder than the 6.5-284. And the 6.5-284's wind drift at 1000 yards with a 140-gr. bullet is the same as a 190 SMK from a .300 Winnie. The 1000-yard wind drift difference between a high-BC 140-gr. bullet leaving 2820 and 2970 fps is about 10 inches, not about 4 inches.
I think the barrel life numbers are wrong, but barrel life claims usually have a wide range. Barrel life is inversely proportional to shooter’s accuracy skills. Folks who don’t shoot very accurate claim longer barrel life than those who do.
