Update #2 on my load. Settled on the 75 gr load with the 142's. Kept shooting the rifle (factory new one) and about the 100th round down the pipe I noticed the group opening up a bit (up to a .8" group for 3).
I pulled out the Magnetospeed and shot a 10 shot string over it. I'm guessing my barrel finally 'broke' in. The same 75 gr load was bumping down the road at 3240 on average.

Took a nice 5x5 with it this fall. The 142 cleared through both shoulders at 137 yards.

I'll keep playing with it as I really enjoy shooting my 264. Picked up 8 lbs of RL 33 and 800 bullets (i'll use some of those in my 6.5 Swede as well). Should last me through my first barrel though.
