Ok, I did a bit of digging and found 460 rounds of 6.8x51 in a metal ammo crate listed at just over $1200. I’ve also seen two military ammo boxes, bundled together, listed as a “case.” 920 rounds plus 2 ammo boxes for $2400 is pricey, but not ludicrous. At least, not when 6.5 creedmoor can be found at $40+ per 20.
