Grendel vs 308

Let his data stand and we'll see what he's got. If nothing else, we can all learn something. Shooting at long range has a zillion micro variables.

For example, you can throw a football with a perfect spiral and it flies beautifully. But throw it badly and it wobbles like a duck. Same with bullets. If your barrel puts a beautiful spin on your bullet, it'll fly far and true. If your spin is less than perfect your bullet will wobble slightly and its frontal area will effectively increase, reducing the BC. Just an example of things that can account for performance differences between barrels.
