.243 Winchester cases feed smoothly
A better combo of autos and .243 Winchester need yet to be discovered. I've fired thousands of .308 Winnie ammo as my designated duty, and never found a dud that didn't work. Military ammo meets Mil-Specs. Why would Military 6mm ammo be less reliable? One day, my mission was to personally fire 200 M-14s with 20 rounds each. Of course, I had loaders at my side, and Korean children attempting to police my brass. They got a fair share. I tested our entire battery of M14s that day. Camp Snow was a small "group" stationed 6 miles south of the DMZ. I was in charge of twelve great guys, and loved every minute of my year and twelve days there, except for some strange days.
