Update: I've had it out to the range a few times now trying to nail down the perfect load with the 130 VLD's. Finally found it today!
It was kind of erratic the last time I took the Kimber out, running 2-2.5" groups on average, I was running at max loads (and a little over) trying to get the most speed out of it I could. I found that my hold on the rifle had a large impact on accuracy, too. This lightweight likes to be snugged up on.
Anyway, backed the load down for today's outing to 43.5 grains of H4350 behind a 130 VLD in Lapua brass and got groups measuring right at 0.5" at 100 yards. There were three groups, so I'm satisfied it's not a fluke. Chronograph showed 10 FPS standard deviation. 2820 FPS 12 ft from the muzzle. Perfect. I realize now that my upper end loads were pushing pressure limits and were most likely somewhat over, and that thin barrels like this can sometimes be picky. 43.5 grains seems to be the sweet spot for this bullet in my rifle.
Happy as can be, and the 140 grain load still shot as well as it did every outing, Chrony showed 2710 FPS average with 42.7 grains H4350, so I picked up about 15 FPS with the Kimber over my old Savage. Great!
This thing keeps it up and I'm gonna end up buying a WSM Montana to keep it company.

Thanks for the update. How is the scope treating you?

... I found that my hold on the rifle had a large impact on accuracy, too. This lightweight likes to be snugged up on.... That is a fact with the Montana. I found a firm grip, but not too firm, results in excellent and repeatable accuracy for me. Basically as if shooting offhand, but with a light assist from the bags. As a note, the same load shoots <1" with me holding it, and >3" if off a bipod with a rear hold only. I'm slow, but I learned...

Thanks for the update. How is the scope treating you? I like the Leupold 2-7x, WIDE field of view at 2x, and 7x is more than enough to hit game at 600 yards and in. The rifle is very light with this scope setup, which was my primary reason for changing to the Leupold over the Vortex. As a bonus, the LR duplex drop points match my 130 grain load really closely. I don't normally hunt past 200 yards, but it's not unheard of out in West TX so it's nice to have a visual reference without needing to dial elevation.

Outstanding pickup!
The 260Rem sounds great.

Rye, my Kimber MT 260 shot just so-so with H4350... when I switched to H4831sc and 120-125 gr bullets, the groups shrunk by more than half.

Thanks for the info, I ended up with H4350 because I already had it on hand for my father's 243 I load for, but I'll definitely give H4831SC a try if I ever switch bullets.
