I got to say thank you to Oldoregan , my grandpa has been a rancher all of his life , he is 84 now . He carried a 30-30 and used it to kill black bear and plenty of elk too . We spoke about all the new calibers and he was just amazed at what these new bullets do , but said dead is dead and that his 30-30 would tumble anything on four legs here in NM . He used .22 long rifles for most of his life , killing many a coyote that wondered too close to his sheep or cattle . These days a .22 for yotes or a 30-30 for elk isn't really a choice many an outdoorsman chooses , but to ranchers these two calibers still are a vital piece of equipment used effectively ....With that said , I killed my very first muley with an open sighted Stevens bolt action 30-30 that my grandpa gave me for my 13th birthday , couldn't recall what grain of bullet , but brought home a deer with my grandpa and dad right there with me some 17 years ago . Elk are extremely TOUGH , and it wouldn't be my first choice in calibers but it all boils down to shot placemeant and if you planned on 100 or so yards being max distance and was pretty handy with your 30-30 , either 150 or 170 grain will do the job ....May get hammered by ballistic junkys for this , but I'll just take my grandpa's experiance on this one ...NMhuntnutt
