That is an excellent price. FYI, be aware that it is bi-metal (magnetic projectile) per the additional info. Nothing inherently wrong with that, but it may limit where you can shoot it (range restrictions). I would have ordered some 7.62x51 if it wasn't bi-metal.
I have been shooting this Swiss ammo (non-magnetic). It currently can be had for .715 cents/round. The shipping is free but i don't know if they charge tax.
