Hi all,im new here and have a few diffrent boxes or cans of ammo that i would like to know a little about.One is this International Match 1956,Frankford Arsenal.It says 7.62 MM Ball,T275E2,172 GR B.T. Bullet,Primer Rem.72,Powder IMR 4895, Velocity 2640 + - 30, Lot FA 4. It also has PRACTICE stamped on the box in Red,is this worth anything or should i just shoot it up ? I would like to know a little about it first. I have several cans of Match Ammo and also one that is marked XM118 from Lake City, what does the X mean ?
