That seems pretty damn fast to me, especially considering that the 264 Win Mag will only get around 3200 fps and the 6.5mm STW will only get around 3300 fps.......
Sounds like you either have a VERY special barrel or your pushing things a bit hard.
For what it's worth, I've just finished barrel break in and starting load development on my 6.5WSM in a 26" Broughton barrel (1-8 twist).
With H1000, GM210M primers, Berger 140 grain hunting VLD bullets, max load for me with these components is at 67.5 grains ( I got the slightest sticky bolt lift at 67.5 grains on a couple of rounds but not on all at that charge). At 66 grains am getting 3120 fps.
