OK, you are looking for a scope in the 1-24X range. Which end do you want to compromise? 4-16X, 3-12X. Pick out some numbers. With the practical shooting range of the 308 in a shorter barrel and on man size targets with close range practicality, I think I would go with a 2-10X. Nikon Monarch 2.5-10X42 would be an example not necessarily a recommendation.

"As democracy is perfected, the office of President represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be occupied by a downright fool and complete narcissistic moron."
