I hear a lot of talk about a lot of various rounds, but the .308 isn' t mentioned too often.
The .308 has become a ho-hum round in the world of superduperultrashortmagnums which get all of the publicity in order to try to convince people that their new wondermagnum is a much better buy than a .308 for the average sportsman. The .308 really doesn' t need any publicity to get sales because its been time and match proven to have excellent accuracy, low recoil, easy to tune, reliable, and powerful enough for darn near anything you want to hunt.
I love my .308 and wouldn' t trade it for a 30-06 or anything else for that matter. I don' t think there is any advantage for the 7mm-08 over the .308 as its very similar in bullet size and ballistically. If I were to buy another .308 class rifle, it would be in .260 rem, since its similar to my second favorite cartridge the 6.5x55 Swedish.
