Writing about his M1 carbine, Dr. Ralph supplied the theme for this gunfight: Big Boys' .22s. Both rifles were designed for shooting more than paper and tin cans, but these two are primarily peaceful plinkers. Critics might say plinking is all they are suited for, since they are chambered for rounds that many argue are underpowered for combat. The Mini-14 is a .223, while the M1 is chambered in .30 Carbine. Both rifles were also designed, at least partially, by two very different American firearms geniuses. Sturm Ruger's William Ruger adapted the Garand action to the Mini 14, while moonshiner David "Carbine" Williams came up with the basis for the M1 while serving time in prison.
