I am shooting a savage 112 BVSS 7mm rem mag and was shooting groups of about .5 to .8 inch at 100 yards which is fairly good for me. So I decided to move to 200 yards. I shot 10 shots, 7 were about 2.5 inches low and in a good shaped group however the other 3 did not drop at all but were also in a fairly tight group. I am curious and frustrated as to what would cause two sub-groups like this /ubbthreads/images/graemlins/confused.gif. Any insight to my problem would be much appreciated.
