I have a goofy ? why would you get a 45/70 in a 15" instead of the new Katandin(not even close I bet) factory barrels which are 18" barrels. Obviously I guess your planning on a 45-70 pistol if thats the case with the shorter barrel why not the 454Casual. I think that might be a better choice with a 15" barrel. IMHO

Im just looking for your opinion not stating your doing something wrong.
