Case Capacities:
30-06 - - - 68.2 gr
30 Gibbs - 71.12 gr
3 gr of powder... I have better use for my money and time.
I appreciate the Gibbs as a theoretical concept but I like the 30-06 more, it always does everything I need a rifle to do.
If you're impressed with the 30 Gibbs my 300 WM will absolutely blow your mind...!
I've measured the gain in based on water to the top of the neck right @ 10%, not the <5% you have posted.
