Its all 7.62 x 39. Some of it is loose and some in boxes. The boxes read: CENTERFIRE AMMUNITION CAL. 7.62 x 39 HP L. C. B. 123 GR. BALL MADE TO HUNTING SPECIFICATIONS KEEP OUT OF REACH OF CHILDREN Other side of box: MADE IN RUSSIA 20 PCS Headstamp: 711 94 The case and projectile both strongly attract a magnet. Next is 10 rounds on a stripper clip with a headstamp 31 64. Both the case and projectile strongly attract a magnet. So is it steel core, AP? Is it worth anything? Thanks.
