Re: Range ammo for AR15
I personally don't care for the laquer-coated steel cases that Hornady chose to use on this ammo (saves costs...sure, but can cause a lot of problems). It seems to have the same effect as other lacquer-coated ammo choices (Soviet bloc stuff) which results in stuck cases in your chamber, etc.
For the money, you would be better served to get any number of different surplus options like Federal/Lake City XM193 (or the black-box Federal/American Eagle XM193). This can be had for around $0.35/round from places like Ammunition To Go, etc.
Also, if you don't mind spending a little more for quality, the Black Hills 55gr Blue-box. Triad Tactical (a site sponsor) sells it for around $0.46/round, but it is very good quality, consistent, a great for everyday shooting/pinking/practice ammo at half (or less) the cost of match ammo.
