You know what I dont get, is how they are claming that the .30TC makes the same power as the 30-06 with a shorter case of the same diametrical dimensions. Maybe their factory loads that they have developed have the same power as your basic 30-06 factory loads, but that is because they are using special development. I know that when I load my 30-06's, I am using anywhere from 95-102% or so of my case capacity. So for me, smaller case=less powder, no matter how you look at it.
I see it failing. I don't know about others, but them saying they are trying to make a case "better" than the 30-06 and therefor why use the -06 is the dumbest thing I've ever heard. I think I'm gonna go look up some load data for it...
