I bought a box last summer just to see how it shoots. I have a box stock 10-22 and a Clark custom that both shoots it quite well....quarter size groups at 50 yards..slightly bigger for the stock 10-22 and just under for the Clark. My S&W M&P 1522 shoots it pretty much improve cylinder......4-5 inches at 50 yards. Haven't done any killn' with it, so I can't tell ya how the bullet performs in that situation. Just like all 22 rf ammo, some guns will shoot it and some won't. As expensive as it is, I won't be buying any more.
