[QUOTE="JEVapa, post: 3975309, member: 41176"] Any smaller than .5" 5shot groups and they should be stacking. A .308 is Three Tenths of an inch. Two .308s side by side is over .5". The smallest possible group (hole) you could ever get is three tenths of an inch (.3"). You are probably good. I'd be happy as clams with that load, especially if it's going fast and is consistent. If they are stacking, you have to find the center of each. At 800yds, a .5" group will be approximately 4". Just the dispersion will keep you from getting much smaller than that. If you are able to repeatedly get bullets stacking on one hole, you best group would be somewhere around 3" at 800 yds. Maybe 2", but I've not ever seen a repeatable group like that happen. That's in the vertical (always measure vertical). Horizontal always has environmental or shooter effects. Recommend you stay away from ShootnCs for groups. Recommend paper with 1" grids and a good gray/black aimpoint. You'll get cleaner measurements from paper, and should be able to measure center of the holes. [/QUOTE]
