shootem, 30-06 for me. But just because I can't leave well enough alone, I own a reamer and it has a 0.337 neck (0.340 is SAAMI) and a 1.5 degree leade (3 degrees is SAAMI for the 30-06). I have to neck turn Lapua brass, but all other brass fits without turning.
They are 5R barrels, but after shooting 5R barrels from Bartlein and Rock and a 4-groove barrel from Brux I can't tell a difference between any of them with respect to the groove configuration.
I think you will like the #2 more than the heavier contour paired with the Kimber action. It should be a great rifle. I also put Dyna Bore Coat in the bore for rust protection, and plan on using Dyna Gun Shield outside the bluing once complete. Then the rifle should be as protected, or more, than with a SS barrel, but still have the gloss blue appearance.
