Tell me when the RP hits nightfall.
-Oh, and
I'm going to encounter a UAV near the airport, and like seasons 3-4 in the series, it'll be a bad omen.
Yes. They have more ammo but they are heavy and cumbersome. Also I do belive the jam and are hardr to fix.
Heavy, expensive, the mainspring breaks easily, and the 'can shaped drum was made of thin metal and could easily get dented.
Oh, and if you reloaded the drum incorrectly (to do it right, you had to release the mainspring without breaking it, and disassemble the drum, then place the bullets in the drum
correctly, then re-assemble the monster, in the dark, starving, wet, literally covered in mud and shit, while being shot at.) The spring also had to be re-wound up
just-so and often needed to be given a "boost" about halfway through or the lack of spring-pressure would cause a failure to feed.
The inside of the drum also had to be kept oiled and clean. But oil attracts dirt and mud, see also method of topping-off a drum and how much it sucked.
If you tried to crank it down all the way to avoid the need to crank the drum halfway-through,
you'd often be rewarded by hearing the spring snap-off inside the drum. Now it's just an inert twenty pound steel ammo-box/paperwieght. Twigs getting into the drum-arms could also jam the feed.
Drum weighs nearly five-to-ten pounds once loaded (depending on 50 rd or 100 rd drum). Although the drum is beefy enough to take some abuse when empty... imagine hitting the mag of an M16 with a sledgehammer... that's what happened to a fully-loaded Tommy-drum
nearly every time you fumbled and dropped it in combat.
Stick mags... weighed quite a bit less (a quarter of a 50 rd drum), and were a lot less likely to smash themselves like a snow-globe when dropped, they also didn't need to be disassembled
nearly as often, so less mud in the mechanisms.
The PPSh-41 mags and the soviet insistence upon using them is another matter; for one, the ammo weighed quite a bit less, and they never tried stuffing 100 rounds into a single can. (in fact, many times the drum wasn't ever quite full due to supply issues)
