Yep, we should've stayed with the .308 M-14, which was a damned fine rifle.
The M-14, which I carried at Parris Island, was an OK rifle, but my personal favorite for overall reach and hitting power is the M-1 Garand. I have one now, but I carried it first during infantry training at Camp Geiger in ‘67. (We used a LOT of WWII and Korean-vintage stuff, INCLUDING C-rats.)
