Sighting in too far out will give you a really high max point blank, which sux for hunting. I sight my 7mm saum at 150, which makes it 1 1/2 in high at 100 and dead on a 50 also. max point blank is inside on inch. at 300 mine is 8in low like this, 200yds is 2.5 in low and 4in low at 250. 26in low at 400, which is the farthesy ill shoot at a deer.
