What a differnce from the red dot. At 40 yards with my stacked red dot once it was sighted in for 20 it shot a foot low. With the Excaliber Drop Zone that I bought from Digger it shot right on at 40. Much nicer having some magnification too. Thanks Doug I appreciate it. Did not have to adjust much either It was pretty much on but shooting a tad high and to the left.Got it set good now It was pretty hot out there today so I am going to wait for a cooler evening and go shoot again. While sighting in I had 4 arrows touching at 25 yards while shooting the first time at the target. Like I said it was off to the left and high from the bull but the group was amazing. I can see how easy Robin Hoods can be using one of these with a good scope. I did not nick any arrows but they were very close to touching shaft wise and the feathers were all touching or pressed together. Just a fraction either way with any of the arrows would have been a damaged arrow or a Robin Hood. The red dot I had just did not shoot this tight.
