"Sometimes skill is not the best substitute for a big gun." - Technocracy: Syndicate
I have had a number of people over the years tell me that you can fire 7.62x39 out of a 7.62x51 fire arm. I was even told on a course during work up training for 03-08 by a Sgt that the reason the AK74 was chambered in 5.45x39 is so that they can use our ammo in their guns if they run out.
I hate experts
