Just picked up 160 rds. of 7.62x51mm NATO marked ammo at flea mkt. Thought I got huge bargin, but when I got home and refigured I had paid $.45 per rd. ($72 for all 160). This is beautiful clean stuff headstamped BF 79 68 and NATO circle with + in an opened heavy green plastic carry bag. I checked on headstamp and it seems to be Portuguese? I know the bargin went out the window, but at least did I get it for a 'reasonable' current price?
