I have suspected the ammo is not the most accurate ammo out there, but it is at the moment THE BEST ammo as it is free, supplied by my LE agency. Some of the guys reported better accuracy with the Federal AE223 they used to supply, but they bought a pallet of the Hornady as they got a better deal on it.
Only SWAT guys are allowed to carry rifles on patrol, I was just tagging along with my personal AR to get some trigger time with free ammo this morning.
And I am new to AR's, this is my first AR and I've only had it a few weeks, this was the third time I have shot it.
The good news is it has been 100% reliable for over a thousand rounds. It got 500rds through it today.
