Not in my opinion. Heavy loaded .45-70s can have some thump. I do not shoot any scope that does not have at least a 3 inch eye relief unless it is on a .22 LR. which is why almost every scope in my collection is a Leupold. Even if ported a 405 at 2K is going to give you a good case of scope eye unless your rifle weighs 15 pounds.
Eye relief of 2 inches would not be for me. Also take into consideration your shooting position AND the recoil pad. For instance, the LimbSaver,although a great working pad,takes away about 1/2" of eye relief due to it's flexing during recoil.
