with maybe the exception of an elephant, i could just use my old lever Winchester 71 348 . but to be honest a 300 WIN. MAG would work just fine for me in my Ruger #1 for all except a elephant. i have in the past killed a large bull bison , a huge bull elk that scored 376 B.C. and a mountain lion with one shot kills with my bow and arrow so i see no reason i need anything bigger than a 300 Win.mag.. also remember Mr. Bell killed many 100`s 0f elephants with a 7x57 mauser cartridge one shot kills.
