Agreed, but the velocity difference with same weight bullets is not anywhere close to the case capacity difference. The 7mm is 100 fps faster with some bullets...not significant in my mind. I know its a wierd comparison. The 7mm is definately a better long range round because of the higher BC, etc.
With todays tough bullets, I like lighter and faster, which definately gives the nod to the 7mm mag. I shoot 150g TSX in my 30-06 at 3000fps and it matches my reticle perfectly to 600 yards. A 7mm mag would do the same thing with a 160g. Again, not very significant. But when you step up to a 180g going 3000 fps there seems to be a significant gain in damage to animals large and small.
I just think the two (30-06 and 7mm)are very comparable in killing power, and a 300 win mag is a definate step up.
