Yeah, I find to say one rifle does not shoot well across the board is absurd. You might hear that stuff about every rifle out there. The problem is that you do not know how the scope was mounted, if it was in good shape, how the barrel was cared for, how it was broken in, how the barreled action was mounted in the stock, the elements the rifle was shot in, the ammunition used, and finally the rifleman's skill level. Just way too many variables to say a gun does not shoot. Kimber rifles have no reason to be inaccurate. They have all the necessary features to get you started in the right direction.
Well as far as shooting, I have only tried some handloads from a previous 300 Win Mag. I can tell from what I did shoot thus far the rifle is very capable as is. I get real world hunting position groups of 2.5" @ 250 yards in a 5-7 mph breeze with 200gr Nosler Partitions loaded hot. At this range just your pulse bounces the reticle around the bull. I am certain the rifle is more capable if I was to use a vise or sandbags. I find with the Kimber rifles there is a load it prefers, finding that load can be entertaining. I am sure there are better loads for this rifle, I need to try several 180 grain bullets and powder combo's to be sure.
