Probably, but it means dedicating a shotgun to just scope style deer hunting. I could do it, with my plethora of 870s, but haven't since what I use works so well.
I've no experience with cantilevers, and my experiences with saddle mounts were not good.Keeping a zero past 5 or 6 shots seems impossible. Maybe they've improved, but I'm not holding my breath...
The KISS principle applies here. Many repeater receivers are thin metal, and getting enough thread is difficult, but possible. Once mounted, I'd be tempted to leave a scope on permanently.
With my old eyes,going to a scope would make sense, but I'm doing OK with the peep. I am switching over to LH, the eye on that side focuses better than the right. Last doe taken this last season was a left handed shot.
