This isn't bad ammo. It was surprisingly clean and didn't gum up my rifle as much as I expected it to. But it is still painted steel case ammo and brass is better. I had some issues with jams, ejection, and general cycling that I believe were caused by the "grippiness" of the painted steel. 6.5 grendel ammo ain't cheap, so this is good for practice. But I would recommend brass for situations where you need to trust your ammo.
Also keep in mind that this is 100 grain, which is lighter than most other grendel bullets. So adjust your ballistics calculations accordingly. Word on the street is that its coefficient is around 0.4 and muzzle velocity from a 16" barrel is around 2590.
