This is top of the line, American-made range ammo made by ATK at the Lake City Army Ammunition Plant (ATK is the same company that makes Speer Lawman, CCI, Blazer Brass, etc) - it doesn't get any better.
Note: This product contains steel in the projectile (this bullet is magnetic) as it is made to military XM80C specifications. Additionally, this brass is manufactured on mil-spec production lines which require evidence of the annealing process be left on the brass near the neck of the casing often referred to as the iris. This is the darker residue that is visually noticeable around the case neck. Both commercial and mil-spec brass undergoes this same annealing process which make the brass stronger and less brittle. The annealing process essentially runs the brass through a series of flames which heat the brass having the affect of re-strengthening it in its final shape. Commercial brass is then re-cleaned after it has been annealed to make it cosmetically more appealing for the commercial market. Military requirements on the other hand place a larger emphasis on the structural integrity of the casing so they require that evidence that the brass has been annealed remain on the brass.
