A buddy has one. 7.62 X 51 surplus has dried up. Gone are the days of $.13/rd German DAG, South African, Portuguese, British (Radway Green), Lithuanian ammo.
Reloading is the only real option these days, but even then inexpensive projectiles are hard to come by.
In life, strive to take the high road....It offers a better field of fire.
