"Does bullet weight really make a difference though, if it's moving 4,000 fps? According to the math, yes it does. .22-250 will shoot much faster and flatter within short-to-medium-range distances, but as distances increase, the bullets slow down quickly and go subsonic long before the 1,000-yard mark. By contrast, the 90-grain SMK moving much slower out of the muzzle will remain supersonic past 1,300 yards. The difference in wind drift is even more stark. The 90-grain Sierra Match King bullet drifts noticeably less than the light and fast 22-250 projectiles.
Does this mean that the 22-250 is now outmoded? Not even close. Varminters depend upon its flat trajectory and inherent accuracy. It's a handloader's dream cartridge, and the factory ammunition out there works well, too. If, however, you want a semiauto platform or you want to shoot longer distances, .224 Valkyrie looks like it will be the logical choice."
truth? or marketing?
