I am really surprised that a .327 rifle hasn't shown up yet. A lever action is an obvious platform, but at least a Handi-rifle and ideally a Ruger bolt action, same as the .357.
No, we don't need one, but people buy what they want as much as what they need.
I understand Marlin has its plate full right now, but it seems like a no brainer to me...
...then again, I thought someone was going to come out with a 5mm Remington Magnum rifle when Aguila started making ammunition for it again.
