I'd say it depends on what you like and what you plan to do with it. In general, the ones I've played with in the standard cartriages were a little muzzle light, and the stock's pistol grip a bit too thick.
But they do meet the needs of a really light, practical rifle pretty well. I just prefer a little more weight in the barrel.
They can lightend further. Things like going to a foam style recoil pad and a few other things can bring them down to under 6 lbs. scoped. E

I saw that step by step build thread you showed a while back Mtn Hunter. If I knew how to do that type of thing, I probably would not own any nulas. Plus the satisfaction in building your own is something that cannot be bought.

I'm just waiting in the weeds for Mnty to get sick of some of his szchit.

I'm kind of in the same boat. Try to find an old style Ti or just go down and buy a Montana? I have decided it will be a 308 and probably shoot 165 grain Trophy Bonded's out of it. I've always been a fan of Remingtons, but the Kimber route just seems easier. I have a friend with numerous issues with her Kimber which is what kind of has me shying away from that route.
