I have killed elk with numerous rifles ranging from an open sight Marlin 336 30-30, 7mm magnum, 30-06, and my beloved .358 Winchester. There hasn't been a single elk I've taken that wouldn't have fallen to the .358. It has become my GO TO hunting cartridge of choice. Unlike most hunter's though, I self impose a 400 yard range limit. If I can't close the distance inside that range, then I'm not meant to take that elk.
