If it's the same parent case as the 28, it will probably smoke both of those, at least 150 fps, maybe 200 fps over the 270 wby with the same sized bullets. Just my guess.
At Elk camp we compared my 270 Wby cartridge next to a 28 Nos...they looked very similar.
My 270 Wby, 28", 1-9 twist barrel. 3225 fps for the 170 Bergers, 3350 fps for 150 SSTs. 3570 fps for 140 SSTs and 3670 fps for 130 SSTs with out any load development.
