Is it even possible to lift and aim a weapon with a 200-round magazine? That great a weight would hamper the capability to move through underbrush with any degree of stealth, and would only be appropriate if in a fixed location where the weapon could be supported by some kind of tripod.
Sure they could 550 box of 22s aint that heavy
The Beta C magazine for the M16 and certain HKs holds 100 rounds.
It apparently worked well at a test in Ft. Bliss and not so well in Afghanistan using British ammo.
Seems like it would be damn heavy.

According to Gun Zone, 100 rds. of 5.56 ammo weighs approximately 3.7 lbs. So 200 rds. would be 7.4 lbs. not counting the weight of the magazine and the weapon itself. So without any accoutrements, (red dot, light, and whatever else) you are looking at probably 12 lbs. for the system. Not horribly heave, but I wouldn’t want to lug it around for hours on end.
