I recently got an American Tactical Galeo, which is basically a IWI Galil - receiver and barrel were manufactured in the US and the other parts got shipped as surplus. I am wondering which 5.56 ammunition to get - how many grains and manufacturer. I'm thinking about getting either the 55 grains or 62 (green tip). I've done some research and found someone stating that the 62 grains were not as accurate for his specific rifle (don't remember which one) and another which said that 62 grains were more accurate for him. There was also a thread about 62 grains lighting up the skies, though I don't know if that was merely grain count or specific manufacturer has some "different" gunpowder. I can always get a few of each and after zeroing might sights, see which one is more accurate, but thought about asking for advice here.
