I don't have any speeds for you,but the 270 Bee is a great round. Mine loved 150 grain bullets,and was a killing machine. I never could figure out why folks hated the brass. Never had a lick of trouble with the shoulder design. It was some of the easiest sizing stuff I ever ran across. I'd build a rifle around the round in a heart beat. keep us posted on the fast twist version should it take shape.
