You are right, Ripp - the 6.5's are more accurate at the closer ranges.

When we're talking 1,500yards and beyond, what many now seem to call long range, the little ones cannot compare due to the laws of physics, of course, neither can the .308.

I was quite astounded, my 30mm Vortec scope got me on the 1,000 meter buffalo's heart, in a mere 2 shots. the Rifle was a stock .300 MAG, Bronwing A3, shooting factory Winchester 180gr. Bonded, zeroed at 200meters.

IIRC, I needed only 27 moa elevation and the scope provides 30 moa correction.
I used this program: The BC's and etc, were all guess-at.
The second column gives moa correction for the ranges. Unfortunately the chart is in yards and I could get it to change it to meters, however the extrapolation is only an extra 9 yards per 100 meters, pretty simple. My screw-up needing 2 shots at 1000, was due to holding for 1000 yards, not 1,090 yards. The second shot was needed due to my flub, oh well. My first shot was just under the heart area, second with correction for the extra 90yards was spot-on.

That scope makes it easy if you have a range finder.
