None of the rounds mentioned spark my interest when paired with a lever action.
What WOULD spark my interest is a Marlin 336 with a half magazine and 26" barrel chanbered to 7-30 Waters, with Hornady LeverEvolution ammo or component bullets.
Since they've got the .308 Marlin Express already, I'll just go that route....
Or, mayber the .338 Marlin Express.......
What I really, really, really want, though, is not a NEW lever action platform. I'd like a new Savage Model 99 Featherweight Takedown in .250 Savage!
