I'm guessing here also, but after looking at the velocity figures I find, 3200fps should be attainable with that length barrel. Looks like the slower burning powders are going to be your best bet.
I haven't found the Bergers yet either. I think you can put an order in directly to Berger. I saw the phone number mentioned in another thread here. The other day when I was on Midway looking for them, I did see that Nosler is coming out with a 110gn AccuBond for the .270. Probably for the 6.8SPC shooters.
With my Coyote M70 in .270WSM I'm getting .5" and better with 66.0gn of RL22/CCI BR2's/130gn NBT and 61.0gn or IMR4350/CCI BR2's/135gn SMK. Haven't chrono'd any loads yet, but that's coming soon.
Anybody else got any load data for the .270WSM they're willing to share? JohnnyK.
