Nice rig!
I, too, am a fan of the 6.5s, and there are more guns/barrels in my home with that bore diameter than all the rest combined. I am currently shooting a 26" Contender barrel by MGM in 6.5 Bullberry Imp (aka 6.5x30-30 AI) and absolutely love it.
It is set up with a 1:8 twist and throated for the long 140 grain boat-tailed bullets, but it shoots everything -- including the stubby 85 grain Sierra HP -- with enviable accuracy. I got a bunch of Nosler 125 grain Partition seconds for less than $20 per 100 during the recent Nosler Shooters Pro Shop sale, and my fireforming loads (minimal ff since I am using eabco.com's 6.5 BRM brass) are shooting consistent half-inch groups. I actually have these in my cartridge carrier as I plan to air out a hog or two over the holidays. I had been using the Sierra 140 grain GameKings for that purpose, but they are so predictable in performance that they are almost boring -- in a good way, that is.
The 125 grain Partition at 2700 fps should do equally well...
