I tried to find anything on this in back commentary but couldn't. As there are many here with MUCH more experience than me with large bore rifles, can I pick your brain? Big bore, dangerous game, double or bolt rifle, how about using a larger apature ring rear sight instead of a leaf? Also smaller ring for plains game hunt. I am thinking of my next safari also (plains game only) and maybe I want to do an iron sight hunt this time. I used ring sights. I actually liked them. What are your general thoughts?
