Geedub, I load my .350 with 200 gr Horn spire pts and a starter dose of TAC for 2725 fps for Whitetails. It shoots that easily under an inch @ 100. On the farm I have a makeshift range maxed at 340 yrds and the same recipe will shoot 2.15-2.25 at 340. We have run the 200 TSX up to 2925 with TAC and good accuracy...but the Elk didn't cooperate.
A couple of years ago a 673 6.5 followed me home. Last year I hastily scoped it before Deer Season and the second load with 125 NPT went into .800 @ 100 at a sedate 2900 so it went hunting with that. Lots of load work to do but I expect to see 3000 with 130's...albeit the 125 load feels like a .260 at the shoulder and thats hardly a bad thing.
In my mind for a factory rig in odd chamberings...the 673's want to shoot.....
