Today at an auction I bought some 30rdns of 7.62 Russian ammo. They are kind of unique because they are "precision reloaded" milsurp rounds with sp 174gr bullets. They are done by the Finnish for interarmco and have date stamps from 1939 to 1943. They also have a price sticker that says $4.69. Non-corrosive berdan primed. Are they collectors items or should I shoot them up? Cool stuff.
