My AKs chuck with authority. I'd say 15 to 20 feet when I am shooting offhand. The Yugo surplus is hotter and lands a few feet farther.
My M1A with any of the 147 to 150 gr milsurp(ish) fodder I've fed it has been a decent 10 to 12 feet, mostly to the 1 to 2 o' clock position. Sometimes I catch a ding in the neck or shoulder, but nothing too brutal. Haven't started reloading for it yet, so I've never mic'd the cases so check for stretching. Heard the M1A can be tough on brass, but externally to the naked eye, nothing too bad thus far.
My dad's pre-Ranch Mini-14 isn't too bad. I'd say about on par with the AKs shooting anything respectably hot--like any of the M193 stuff out there. My uncle's Ranch Rifle on the other hand, well, there has to be something wrong with it. It launched brass over a trailer once. Never found it. Over the trailer and into the woods...the brass we did find was usually about 50 feet away, split, and mangled.
I would think that a properly adjusted FAL shouldn't be too bad. The roller lock HKs on the other hand are notoriously violent. Casehead separations as well as dings and neck splits seem to be more of a problem with them than the gas operated rifles. This in addition to the longitudinal dents the rifle can impart due to the fluting of its chamber. The design is generally reliable, and most of these aliments don't concern reliability, but it can apparently be tough on brass. Which is fine, I guess, because the rifle really launches them, so by most accounts reloaders just give up.
