So I created this target when I was trying to figure out something that would be easier to zero my muzzy with peep sight. I have never been that great at open sights so this helped. I was having a hard time because the front sight would cover up so much if not all of the big circle on my target. So I tried the 6 o'clock hold method. It worked but I was still having a hard time keeping the sight picture the same for every shot. So I put 1-2" thick black stripes that intersected at where I wanted the "bullseye" to be. This was the trick for myself. On this target the bullseye would be the 6 o'clock hold on the big circle and dead center on the small circle. The big circle I make just about the same size so my front sight covers it entirely at 100 yards. The small circle is about 4" or roughly what my front sight covers up at 40-50 yards. What makes this so perfect (at least in my case) is that on the white paper I am using, those black lines are very easily visible through the sights at 100 yards. For myself it is extremely easy to hold at the crosshairs, just make sure the verticle and horizontal lines are going straight through the front sight in the sight picture. Shrunk my groups by half.
Just thought I would share and maybe someone else can try it and see how it works for you.
