My 2nd & 3rd elk were taken with a .30-30. The same one that my grandfather used to feed his family deer and elk for 40 years.
My 1st was with a .257 Roberts.

None of them bounded over any hills or required altercations with other hunters.

Of course I now shoot .300 Win Mag, but that's because I'm using a Ruger No.1. The single shot action is my excuse for using an elephant gun
