I have a Simmons 4X32 with the Pro diamond reticle. It has been on a couple slug guns and now lives on my muzzle loader.
I have been having some mixed feelings regarding it of late and some of it may have to do with my eyes getting older. In some rather hurried situations recently I have found this reticle to be more of a distraction than an aid. The diamond was intended I think to help focus your attention but lately in low light or inclement weather I find it in the way more than anything else. I do however appreciate the more ample eye relief compared to my other Simmons 1.5-5X This scope requires me to crawl it somewhat, and on my bolt action slug gun that is not something I'm keen on doing.
I have family that are on a Leupold kick of late, and they make a fine product. I am considering getting one of their 1" 3-9X and try it on my "less than cutting edge" CVA muzzle loader. If it significantly improves performance on that rig I will leave it. If not I will stick it on the bolt action and enjoy the much better optical quality and increased eye relief needed for that situation.
