Depending on the weather and my mood, I use NE Ultra Slug or my Knight MK85 for deer hunting. When I pour over the online manufacture's articles, they always seems to suggest to sight in 2"-3" at 50 yards (or whatever based on their ballistics recommendations) for it to hit the bull at 100 yards. Reason being it avoids crosswind drifts better and prevents unneccessary scope adjustments that can occur when sighting in a 100 yards.

I've always suspected my sighting in issues was due to my crappy shooting rest but I just go a Bull's Bag and a Protektor rear bag - this setup looks rock solid! But back to my original question, how many concentrate on the 50 yard distance when sighting in? Thanks.
