Last month in August I bought my father a brand new Color Case Hardened Henry .45-70 Side Gate. I had a few questions about ammo and a scope. Because the rifle is .45-70 should I buy him a rifle scope or a muzzleloader/shotgun scope. Just asking since .45 Gov isnt a fast mover. Secondly, what ammo is best. I was going to load up some .45-70 with my brass and .459" 405gr bullets I use in my Remington-Lee and Martini. Would .459" work for a Henry ? I contacted Henry and only got back a reply that stated that factory ammunition is preferred to be used in their rifles. I guess for legal reasons ? I know my Siamese Mauser Navy Arms runs a .459" no issues while my grandfather's NEF Pardner liked a .457". I was also looking at factory ammo. What is better in one of these Henry rifles the Remington 405gr or the Hornady Leverlution ? Those are what are in stock at my local gun shop. Thanks to all who reply.
