+1 with Ray...Why???
It sure is limiting and not suited to a lot of hunting, but it does make a hunter out of you...so...why not?
Your experience has been negative with the 45-70?
It isn't very suited for my area with the longer shots we have to take often, but I have never had any negative experiences with the 45-70. It just isn't an open country round, compared to the later smokeless-based rounds or even the 30-40 Krag...
I love to play with my Trapdoor Cadet Mdl, however.
