I like the idea of a 357 lever gun--good all around fun gun. But I think we need to define "long distance tack driver", as there is a difference between 100 yards (what I'd call long with iron sights) and 1,000 yards (what I'd call long under any circumstance). I think you've got your bases covered (although I'm not quite sure what the 308 is, if it's a tack driver or more tactical than that). Only thing I can see really missing is a tactical 22 handgun. Cheaper trigger practice than your 40 cal.
