Manufactured at the Lake City factory, this mil-spec product is brand new, brass-cased, boxer-primed, non-corrosive, and reloadable. This is top of the line, American-made military contract overrun ammo made by Federal at the Lake City Army Ammunition Plant. This ammo contains steel in the projectile (MAGNETIC) as it is made to military 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. 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 makes the brass stronger and less brittle. The annealing process essentially runs the brass through a series of flames which heat the brass having the effect 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.

This ammo came in to us linked 4:1 with M33 ball / M17 tracers, but we de-linked some and this is what we have left.

This ammunition is newer production ('16 headstamp), non-corrosive, in boxer-primed, reloadable brass cases.

This is for (1) one bag of 10 rounds.
