The Sub-MOA rifles are flat-out guaranteed to shoot sub-moa, and are supplied with a target attesting to that fact. They sell for $860, and you will probably have to spend a few more bucks having the trigger tuned, but it is some bargain. I don’t know if Weatherby puts an accuracy guarantee on the Accu-Mark, but the one I have, a .300 WBY, shoots three loads into .900-inch, .903-inch, and .670-inch, which suits me fine. It is not a cheap gun at $1,800, but think of it as a $4,000 gun at a bargain price. They really take some pains with this one. Excellent fit and finish, decent trigger (but no better) and one of the smoothest barrels I have looked down (up?) with a borescope. It would be very interesting to load it with match-grade bullets and see what it does.
