To expect/demand MOA or better with factory ammo in a 5-6 lb. rifle is really asking too much. You might find a load or two that will, but I wouldn't bet on it.
Really light rifles, by nature, seldom shoot many loads well.
I suspect that most of the so called problems with the Kimbers are simply the result of the new owner not working with his rifle enough to find the right loads.
But, to answer your question, the NULA's. E
My Mt Guides in both .308 & .243 shoot 1-2" groups, when I do my part, on a pretty regular basis. Just have to keep an eye on the barrell heat... 150-165grn Nosler AB or Partition handloads for the .308 and plain old 100gr Rem PSP Core-Lokt on the .243... I can get better accuracy with the .308 and handloads, just have not loaded for the .243 yet... SUB MOA is not what I expect, but I think I can get there (or at least close) with the right load.
