A bullet from a piece of galvanized pipe will kill an elk, so will a 22 LR, but there are far better cartridges. Not every shot is perfect, and smaller the cartridge, the less room for error. . The 30-30 has killed thousands of elk, but there are many cartridges far better, as there are many better than a 7mm-08. Just my 02, coming up on my 56th elk season.
