This would depend on how far you have the sight extended. I am currantly using a 6x with a 1/4 grind and on a 5 spot I just see the bullseye of one the targets which is the way I like it. When I switch to a 3/8 I see the center and the blue of one target. The 8x in the 1/4 and 3/8 are just to strong for me to use indoors. I use the Bullseye scopes and they have worked out very well for me.
