I have a Kimber 308 and a NULA barreled action in a non-NULA stock. My Kimber is plenty accurate and shoots a lot of loads sub-MOA, but the NULA is easier to load for - I've not found any bullet that won't -easily- go under 1" - but some get lucky with their Kimber barrels and get similar results.

I like the bolt handle clearance and safety on the Kimber better (less clearance with the NULA). As far as ultralight, the Kimber barreled action is actually slightly lighter than the NULA (mine is anyway). I aslo prefer the total stainless of the Kimber.
