I've fired a few. The 249 isn't as hard to fire as you may think. Being a big guy helps. I can fire one like Arnie can in a movie. 7.62 based LMG's are a different story. They're heavy as hell and the recoil is much greater. I've never fired one not on a bipod or tripod.
As for realism, like Kokanee said, limit mag loads to 200. Let 'em carry a couple load's worth, and put a load of 200 on a couple others in the section. Make barrel changes at the proper intervals a requirement. Pretty simple.
