With Barnes bullets I typically start at 0.050 off the lands if magazine length allows. From there I can usually find a sub MOA load with a charge weight ladder without altering the seating depth.
I've never been able to make H4831 sing in my Kimber either. Only got mediocre accuracy, and couldn't break 2900 fps. H4350 and RL19 both gave sub half MOA accuracy at 3050-3060 fps. They would both break 3100 fps as well, without getting squirrelly but accuracy suffered.
53.5 grains of H4350 squirts the 130 TTSX at 3050 fps from my Kimber Montana. I can get another 100 fps out of it, but the groups open up from sub half MOA to to 1.1 MOA
The TSX and TTSX are outstanding bullets. I shoot the TTSX in multiple cartridges and calibers from .277 to .338 with great accuracy and terminal performance. The original X isn't made anymore, so I wouldn't invest any time on loading it.

The Barnes 180 TTSX has been my go to bullet for moose in my 300 Win Mag. I've never tried the e-tips. They weren't out yet when I developed this load, and it shoots so well I haven't been inclined to try anything new.
All 7600s, carbine in 30-06, rifle in 308, 7mm-08 and 35 Whelen. The 06 carbine is the one that sees the most miles in the woods for days of still hunting or late season drives.
