I have a 1-4 x 20 Leupold shotgun scope on a Marlin 30-30 that I like a lot. It has a heavy duplex reticle. I have been thinking about getting another one for a single shot Turkey gun I have but haven't spent the money yet. It is a 12 gauge single shot and that scope would do well on it my only concern is it doesn't seem to have as much eye relief as other shotgun scopes I have used.
