Back in the late 70's and maybe into the early 80's I ran 180 Sierra boat tails through my 308. I didn't have many powder choices (poor college student, etc) so I pushed them with H380. I shot several mule deer and several pronghorns with that combination. I can't recall shooting an elk with it. I also don't recall recovering a bullet. 180's at 2450-2700 fps are nothing to sneeze at. I'm sure they'll work for you if that's how you're inclined. Good luck!
