Got to call you out on this one. First of all with same twist/same velocity/same bullet the ballistics would be IDENTICAL. Secondly .308s are usually much slower twist so they can't even stabilize the heavy pills at subsonic speed. So basically you are saying a lighter bullet at same velocity is somehow magically better. And we won't even get into the fact that you can acheive all these results with ALOT less powder (and alot more variety than just Trail Boss).
Proof positive that "shooting, building and reloading more than 50 years" doesn't necessarily fix ignorance nor stubbornness.
