None of the bullets I listed above was kept under 2700. Only exception might be the 257 caliber, as it was not checked over chrono.
But I am not a Weatherby type of guy....
Now that you bring up the 257 caliber, I've found it quite interesting the 100gr 257 Hornady hold up remarkably well at weatherby velocities (it kills like no other caliber I've ever experienced), unlike the 180gr Interlock which really gets stressed at 300 Weatherby speeds (in my experience anyway)
The 100 grain 257 was designed with the Weatherby in mind as a factory offering. The 180 was geared for the 30-06 and 308 velocities.
For both the 270 Win. and the 30-06 the majority of bullets commonly available were designed for those two and any standard bullet should work fine. I would avoid some of the dedicated long range loads as many of them are very frangible inside 400 yards.
Me I shoot mostly Nosler's and Barnes, but for C&C bullets count me as an Interlock guy. The Fusions and the Federal version are good too and I get them on close outs when I can.
