ok, since I started this I'll give an update. Besides, sitting home with a nasty cold & was told I should do something because I'm acting like a crabby old bastard...… Very un-scientifically added up the responses, not numbers of elk nor numbers of rifles, just the cartridges. Also, each respondent only gets counted for one even if they have shot elk with several different rifles in the same caliber. i.e., I have killed elk with three different .270 Win rifles, but only count one .270 response. Also, not throwing in the onesie-twosie stuff, lots & lots of that. That said, here are the most popular so far.
