I really like the cross targets at Targetz.com. On one target, I cut out the four blocks in each corner of the cross. This is a template. Then I take and lay the template over the another target and lightly spray some paint over the blocks. Just enough color for them to show well. Then there is a white cross inside the 4 colored blocks. Cross hairs center easily in the cross and the pattern and its center is very recognizable when shooting open sights.

I've got to be honest. I can not stand pointing at a dot. I like a larger reference to point into. I can see target choicebeing a matter of personal preference, but thiskind of arrangement has helped meconsiderably, especially with open sight shooting.
