Just got given a bag full of assorted iffy ammo, which I may or may not blatt off through my SLR, knowing what a bunch of spotters we are I thought I would share the fun: Small red tip bullet, green ring around case neck. 2 sets of markings: 7.62 x 51 MS 226-61 and 7.62 x 51 DAG 106-60. Jerry tracer? Orange tip bullet, marked LG 61 and a small circular symbol that may be 4 dots arranged in a square. I think this is tracer. Large red tipped bullet. 2 sets of markings: K59 L5A1 and RG 64 7.62 L5 A3. I think these are also tracer.
