I think Trial is seeing this kind of the way I'm seeing it at this point.
Per the criteria stated back towards the beginning of the thread for what constitutes a "failure" for this undertaking, this has been a total failure. I've put a bunch of time and money into this, to find out that the rifle won't shoot. I do believe it's simple as that.
Not interested in spending what I'd guesstimate at this point will end up being months attempting to get this rifle to shoot by cooperating with Kimber; the whole point was something along the lines of putting a little more money into what should have been a nicer factory rifle (now, we can argue about what 'nicer' means, but for me it has very little to do with "fit and finish" if the rifle can't hold a group, or even meet its own "guarantee") and getting a rifle that would shoot better than MOA out of the box.
I'll call Kimber CS, of course, and see what they say, but I'm growing very impatient with messing with this rifle. Not interested in getting it rebored for a caliber I don't already have any rifle in, etc. If it won't shoot with 8 or 9 types of the most commonly available factory ammo, it's not what I'd call a "shooter" in any sense of the word, and I have a hard time understanding how any could.
Luke - I may very well be offloading this guy soon enough. I expect a fair price since so many are raving about what great rifles Kimbers are, and this one only has 67 rounds down the pipe!
I've got a Tikka in my possession now to try the same experiment with, or something similar. We'll see how that turns out.
I just don't have time nor desire to 'tinker' with a $1200 guaranteed-MOA rifle to get it to shoot.
