This is going after M855 which has a mild steel core and can penetrate an aluminum soft drink can at 1000 inches.
Oddly enough, prices on-line seem to be holding steady. Shelves are full in local stores.
To be completely honest, it’s crappy ammo. I was on a state National Guard shooting team for 3 years. The consensus was that M855 had more unexplained “fliers” than the 55gr M193. M193 was better to 400 yards. Out to 500-600 yards, the 62gr M855 was better...UNLESS you had one of those uncalled out of nowhere fliers.
One of the theories proposed that the steel penetrator may not always be perfectly centered within the lead core.
