I'm onto a great load! Hornady American Gunner 140s! I may have crossed over into factory fodder nirvana. My Montana loves it.
Just finished up testing factory fodder in my Mesa. 60 rounds of 5-shot groups using the Precision Hunter 143 gr. ELD-X produced 0.83". 60 rounds of 5-shot groups using the same bullet in the Black Hills Gold offering produced 0.86"
The barrel on this Mesa definitely didn't like any factory offerings of the same bullet leaving the muzzle going faster than a nominal 2,700 fps. Group sizes for nominal velocities of 2,750+ were always 1.5" and larger.

It's you and the bullet, and all the rest is secondary.
