Re: berger load question
I've had Walt email me load data for several calibers. In each one I was able to get more powder than what they listed.
Load data is a guide. You have to add powder for YOUR rifle until you find out what max is in YOUR rifle.
Example: in my 7 rem mag, 168 VLD, I think they topped out at 70.4 grains of Retumbo. I got 73.0 grains without a problem. And, I think that was about all that would fit in the case.
