I agree, assuming you keep your bullet weights at 150 grains and down. Bullets heavier than that intrude into the case too far on the .308 and you lose powder capacity. The .308 was designed to replicate the original military 30-06 load that pushed a 150 grain spitzer bullet at 2,700 fps. And it basically did that with that same 150 grain bullet. But, the same advances in powder technology that made the .308 possible (in the 1950’s) have also been applied to the OLD 30-06. So I am shooting a 30-06 load out of my Sauer 202 with a 24 inch barrel that drives a 165 grain Sierra Tipped Game King at 3,000 fps and gives me just north of 3,200 ft/lbs at the muzzle. I handload that, but that same performance is available in factory Hornady Superformance and Sig Sauer Elite Hunter loads. You can’t get there with a .308. PERIOD. Modern powder technology, and modern steel are wonderful things and they enable many of these wonderful old calibers to be elevated to levels of performance that wasn’t possible 117 years ago (in the case of the 30-06).
