Hi flagrum thanks for the reply.
re my issue is that I discovered the distance is set to 0 on startup so the sight is big. setting it to say 300m makes the reticle smaller. I was confused why if set at correct wing span the reticle was more that the "glass" of the sight.
Thanks to doom on the forum that posted on how to get the reticle "smaller".
hope it clarifies my issue and help some one else....
