Coyote Hunter, we bowhunters would probably see more game wounded with rifles if our season was actually after rifle season. I'm sure you're a fine shooter, but please don't assume that the average joe out there, with his brand-new .300 MwhateverMag, is!
With competent hands, Elk is completely killable with a Marlin 30-30. I've seen it.

No worries, I've spent enough time at the range working as the RO during sight-in days to see a pretty wide variety of the shooter skills. Some of it is pretty eye-opening - on both ends of the scale...
First elk I ever saw on a wall was taken with a .30-30, and I've hunted them (unsuccessfully so far) with mine. Never seem to have it in my hands when I get a close shot.
I also know from first-hand experience that shooting skills vary widely with bows.
