You don't need it. I wouldn't buy one but that's me. Won't do anything your tried and true 270 won't do a bit better, if loaded with the right bullets. The right bullet applies to all cartridges. However. Since when did need have anything to do with the next rifle we buy? No one is anymore guilty of that than me. I can't think of a single, solitary reason I can justify "need" for my 3rd double rifle.
I'm just one rifle away from being Satisfied.........
Ya!
