I have never fired a rifle yet, regardless of action, that will not hit a 24"x24" piece of cardboard at 25 yards. And after the initial shot is fired, with the rifle held perfectly still, the crosshairs can be walked to the bullet hole (or lightly above it), and you will be close, or slightly high at 100 yards. With ONE SHOT.
The whole premise of bore-sighting is only to get on paper anywho. I've had them bore-sight scopes for me at the gun shop (years ago...before I knew better)....sometimes they were "close", other times not close at all.
Don't invest in idiots....the market's flooded!!!
