Some folks like to leave the aperture off the sight entirely when hunting, and rely on the aperture housing hole only - known far and wide as a "ghost ring." Some folks swear by the technique, others swear at it. I tend to fall in the latter group, but hey, whatever works! (I simply like some definition in the rear sight. All too often a ghost ring turns into a "no ring" for me. But now that I think about it, maybe since my cataract surgery gave my eyeball a new lease on life I should re-visit the ghost ring.)
