Favorite .308/7.62x51 Range Ammo

I have two .308/7.62 x 51 caliber rifles, an AR-10 and a Galil ACE. I'm pretty sure the Galil ACE eats up steel case stuff like nobody's business, but I'm hesitant to use steel case in my AR-10. Either way....

What's your favorite relatively inexpensive range ammo for your ..308 semi-autos? By "range ammo" I'm talking the stuff you use when you are not looking to get precision rifle results out to 400 yards, but just to get rounds on steel or paper at that distance.

Thanks for your input.

No doubt, MEN 147 grain, its great 1.5-2.0 MOA ammo and you can reuse the Brass for reloading.

500 yards is a breeze. 750 doable with fair consistency.
