[QUOTE="WildRose, post: 1507599, member: 30902"] I believe this is the article you are referring to. [URL]https://www.americanrifleman.org/articles/2017/5/24/unsung-hero-the-mk-248-mod-1/[/URL] Basically it says using the more modern powders we can achieve more than satisfactory results beond 1,200yds using the heavy for caliber offerings up to 220gr by exceeding SAAMI spec for OAL loading essentially to mag length which is basically what most of us here have been dong for several years. It essentially shows that there's very little difference betwen the .338LM and .300wm when loaded appropriately at ranges from 800-1,200yds or so. It's hard to be H1000 for consistency but the Alliant powders showed less variation with temps. My best results have been with RL23 and RL26 rather than RL22 but then I'm shooting longer barrels than they are with their limit being 24" which requires faster powders to achive similar velocities.
