One thing that a great many do not realize, as they have never chronographed their ammo, is that a substantial amount of 30-06 factory ammo is very close to .308 velocities, or at .308 velocities.
Years back I had some green box Remington stuff that someone had given me that was the same projectile weight (165 grain) as the .308 handloads I was shooting. I recall that the listed velocity on the box and what the actual velocity was, was significantly different. Remington's 30-06 was a good 200FPS slower than what the box said. The .308 handloads were faster by a little bit. I don't recall the exact numbers but it was 30-40 fps range.
Agree 100%. Once you spend some quality time with a chronograph, the difference between the 308 and the 30-06 with factory ammo becomes mostly psychological.
