Do not sight your .308 at 100 yards. Look up Maximum Point Blank Range. Use that method to find where you want to sight your rifle. For instance, my 7MM-08 is zeroed at 225 yards. The bullet hits 2.5 inches at 150 yards at 2.5 low at 300. I can shoot from zero yards to 300 yards using my crosshair. That covers most of your hunting shots.
You really need to be shooting your gun at different ranges to determine all this. Starting out with a ballistic calculater is a good start. Then use a solid rest for all your practicing. Once you get used to the feel of the rifle and sighed in start shooting in field conditions. What you do on a bench will never be as good as in the woods so learn your limitations.
