So here is the situation...My Sighted in scope is good to a know and confirmed kill shots out to 68 Yards. i can hit my 72 yard steel target at times, but if i go out to 100 yards, I'm consistently hitting left by almost 2 mil dots. this is in no wind conditions. Currently shooting NOE .249" slugs in 37 gr hp.I have tore the gun down numerous times and bubble leveled the top half and bottom tube to make sure they are both straight to each other.how can i be dead nuts on at close range but way off at long range?The gun is the one listed in my signature. It does have FX no limit rings. i have the adjusters all on the left side of the receiver. they are also both on the rear block and not bridging the mag slot. if i adjust so that i hit at 100 yards, then i'm off right at close range.
