I've never had a 24" bll 270 and using ________'s book I got 3150 with 130s.
All my 7 s have had 24" blls and I didn't and don't feel cheated.
My Black Shadow 300 has a 26' bll. BUT I have not rung it out with handloads YET.

My M 70 Super Grade has a 24" barrel and with RL-26 and a 150 grain NP it's getting 3070 fps. Maybe next year I can get a oryx tag and I'll try the Super Grade on one.
