.340wby 200gr@3200fps... i know you want one...lol.
x2 on the depends where you're hunting, and also what season...
sounds like you're dying to get that 338 marlin express, if so get it.
I talked to a guy at the range that was using a .45-70 lever for deer....wonder how much difference in trajectory/energy the two have...if not much I think I might just get a .45-70, i think both would hit 200yds no sweat...and both take an elk,
