If there is no wind, the 308 isn't that bad. Yes it does have the trajectory of a rainbow, but if you're shooting on a really calm day, it can accurately hit targets. If there is wind, and if you're shooting beyond 600 yards though, the weaknesses of the lighter 30 calibers like the 308 and 3006 really show their weaknesses. It's about like trying to go off road in a 2 wheel drive vehicle.

Whereas my 260 and my 7mm rem mag make busting pigeons a little easier. Even shooting in the same conditions, I was able to consistently hit multiple targets. Granted, I was only about to hit 5 pigeons out of 20 rounds spent with the 260, vs no pigeons hit with 30 rounds of 308 and 20 rounds through a 30/06. This is why I've decided to rebuild my 308 into a 284 winchester. I'll start a new thread for the 2 builds I'm currently working on.
