Tried a 50 round box of the above, wanted to see how they would work in my M&P10, thought because of the steel case and the berdan hard primers they might give trouble. The Smith fired them all very cleanly with good accuracy, in fact it ate them like candy. Can buy them for 40.00 for a box of 50, not a bad price for Hornady ammo. Think I will shoot some more at the range.
