The more you look at it, the 7mm starts to make more sense ... from the old 7mm Mauser, the mystique of the 7x57,the Brenneke and Sharps and Hart, the mild 7-08, the new kid in 280 Ackley, a few excellent proprietary cartridges such as the STW/Dakota ... all the way to the 7 mil mag and bigger has versatility that the 30 cal can only dream about ... personally I believe the 280 AI is the new 30-06.
