Can't be done within SAAMI pressure limits.
I agree with this. My two 270's right now are clocking at 2825fps with 58gr. H4831SC using 140 Acc's (RAR). The Kimber Montana with the same load is 2865fps. I see no need in chasing speed when its consistent accuracy at acceptable pressures using an adequate bullet is what you need. If the number "3" is what someone needs, then move to the 270WSM or a 270Wtby..
