GPM.

I suppose it doesn't matter much really so long as you begin conservatively.
I did find this though: https://www.google.com/search?client...UTF-8&oe=UTF-8

Greetings,
I also found that the Nosler 129 grain LRAB gave almost 100 fps more velocity than the Hornady 129 grain soft point in the 6.5-06 with everything else the same so the heavy jacketed projectiles seem to push up velocity and pressure as well as the mono's. I relly should try some I suppose.
