On this particular morning, my max range to 1,800 FPS with this particularly fast 16" barrel was right at 550 yards I believe. I regularly practice with my 223 and 77 TMKs much further than that. Think consistent hits, in wind, in mountainous terrain, nearly daily, WAY past the guns terminal range.
You can either read and call wind or you can't. You can either shoot from field positions in the mountains or you can't. Leaning on a cartridge that "bucks wind better" no matter the range, is a recipe for misses as I'm sure you know and have seen as well.
Is it "practical" for most? Probably not, but that's because of shooter capabilities. Blaming wind is THE most common excuse I see in shooters, particularly in "higher level" shooters.
