"Spanky". I just this afternoon dropped off my Shikari 45-70 to have a Simmons 2.5X Shotgun Scope put on it. The Shikari is not tapped so I need my friendly "Smith'"
BUT The shop said use large rings........I would LOVE to use the small rings...... Is yours a Weaver Base? and rings???: If so I will call tomorrow and tell him to use the small rings. Also 'm hoping to leave the existing iron sights in place...."just in case"....I do get into an Elk or Buffalo Hunt.

$$$$$?
...............would THIS make a difference?
"Stuart C"; I shoot only Black Powder Cartridge, and only in H&R's. I've heard a lot of good things about using a shotgun type scope with 5 to 5 1/2" relief with Black Powder. This will be my first chance to try one.
If I like the Shikari 45-70 set up this way, I might have to break down and do one of my 38-55's simply because even with my glasses.......man its not fun at times........ hate like hell to admit it.......; anyway, I shoot ONLY Trapdoor Loads in this rifle and from what I have read, I do not think I will find any issues with the scope once its sighted in. In my W&H 38-55 with my "pet" load there is hardly any recoil
