I haven't had the opportunity to shoot one of these rifles, but I did own a Kimber of Oregon M89 BGR in .375 H&H.
I picked up a Shooting Times magazine at SHOT (Feb 2008 issue) which has a favorable article by Greg Rodriguez on the Kimber Caprivi. He does note that the rifle shoots good 3-shot groups, and then does poorly when the group size goes to five shots.
His average accuracy for five, five-shot groups was 2.22" at 100 yards with Win 270 gr FailSafe; 1.79" with Federal 300 gr Barnes X; and 2.12" with Federal 300 gr Trophy Bonded. He was getting groups as small as .493" to .536" for three shots, and speculated there was a bedding problem. (I would have thought it was barrel heat given the symptoms described). Scope was a Leup. VX71.5-6X24.
Greg has posted here, perhaps he will comment.
