I, my wife and a few friends I have loaned the rifle to have killed elk (several of them) with my Mossberg 18" MVP. No problem at all.

I have owned quite a few 308s in my life, and I still own 2. A Ruger SR762 (16.5") and the above Mossberg.

I have chronographed the ones I have owned as well as both of those I still own with various ammo. I have found that 20 to 25 FPS per second is the average difference from a 16" up to a 22 inch barrel, and past 22 " you gain about 18-22 fps at 25" and 26" I never had a 308 with a barrel longer then 26"

None of that made any difference on deer antelope or elk.
