I am ticked off this morning.  I just got done working with my stainless '06 last evening.  After working with 3 or 4 factory loads and finding out it liked 180 gr. Federals best,  I put my last shot last evening 1/4 inch from dead center 10X at a hundred.  This morning, I went down to let the horses out and there was a deer behind the barn.  I picked up the '06 to see if the deer was growing antlers, and I felt something loose.  The factory installed scope rail had shot loose.  I marked everything, took it apart, Loc-tited everything and put it back together.  First shot at 100 missed everything including the 3 x 4 ft. target back board!!  50 bucks worth of ammo down the drain and time to start over.  At least I know what the rifle likes, so it's back to the bore sighter.
