303 surplus, where can I find it?

[2K7]

I picked up 200 rounds of Greek .303 British (headstamp HxP 70) today at a show in Northern Illinois. Nice and clean and .65 cents a round. Supposed to be non-corrosive.

Anyone know about this ammo? The cool thing is, it was loaded into this Vickers July 45 machine gun cloth belt.
