Zeroing my new Scope for 3-Gun

I picked up a Primary Arms 1-6X Scope with ACSS Reticle "Advanced Combined Sighting System". I found this reticle to be very easy to use so far. The grouping I achieved in this picture is outstanding in my opinion. However, I did miss the target completely for 1 of my 8 shots fired. But for my 16" rifle, I like it.
