Easiest way to increase velocity is to simply go to a bigger case.
I played around with a .30-06 AI for a while, fussing over getting a meaningful velocity increase over the standard case. The .300 WinMag did that handily...

Vic you beat me tuit ! I've been here on the 'fire' since 2010 and so many know I'm a speed freak ! ain't ashamed.
There are reasons I like the 270/280, 7 RM, 300 WM et.al. and Velocity is one of em.
* this is important to me * when you don't have time to
1. range 2. read chart 3. dial 4. THEN aim..... speed is your friend.
