"What you will find when you do the math is that most of what the .30-06 gains due to extra case capacity is lost back due to poor design"

Ok, I don't want to get dragged into this, but how is the 06 "poorly designed " relative to the 308?

The only apparent difference is a 17.5 degree shoulder vs a 20 degree? Or I guess being longer is a design flaw, too?

MAP...judicious handloaders have been working with this "poor design " for a long time, just as they have with their modern bolt actions in 7x57 and 257R.

My observation: you throw out a lot of technical jargon, which sounds impressive. But you jump to conclusions based on qualitative concepts, not quantitative data.

Have a good day. I'm perfect happy to agree to disagree.
