Things have changed across the board in the last ten years but I thought the standard issue Army sniper set up was a Remington varmint contour 308 in an HS precision scoped with a fixed 10 power Leupold using 1/4moa cranks and baseball mildots, flinging 175smk's...
Did they go to range calibrated dials?
The 24in barrel on an M24 is quite a bit heavier than varmint contour (but doesn't shoot any better than the best varmint barrels, IMO). The Leupold M3Ultra 10X, later re-badged the MKIV, always had an elevation turret that was graduated in hundreds of meters for the issued 308 load.
