I did not have trouble with my .223 84m.  I sold it yesterday to fund a Savage long range rifle build up.
A Kimber rifle, like their 1911's, are produced in such quantities that they will let lemons slip by.  They are not benchrest rifles by any stretch of the imagination, they're well-dressed field rifles that are relatively accurate.  My best group has been 0.6" using 25gn of Ramshot, 55gn SBK's, and a slightly longer OAL.  This could have improved slightly with more handloading research, a trigger pull reduction, and use of a machine vise (i.e. leadsled) to measure it's true accuracy.  And I'll be the first to admit that I'm a crappy marksman.
Most of my better handloads yielded 1" groups, which is far under "minute of groundhog" for most farmers.  I'd rather should this rifle all day with a Burris compact R/A scope than a Rem 700 or a Savage BVSS.  It also had a magical "feel" after I considered the aforementioned rifles.  It's a slim, lightweight shooter.
