"You mentioned cleaner-burning powder: I’m assuming it’s double based propellant?" They all are, the propellant used in DBP87 just happened to be exceptionally dirty which caused excessive cleaning required or fouling problems would appear quite fast so they came up with a new blend that performed the same but wasn't damn near black powder levels of filth. They didn't change the primer type from 87 to 95 per say, still a double slotted berdan primer, they just switched to a non corrosive blend once again for ease of cleaning issues. (Corrosive is still commonly seen in other calibers as the advantage of corrosive being able to last for decades in storage and still fire reliably was long preferred.) "Not having have much experience with lacquered steel cases (literally 25 rounds through a FAMAS), but the rapid build up of residue in the chamber surprised me. Is this an issue with 5.8x42mm?" There's different reasons the French and the Chinese use steel cases, the French used it in the FAMAS because the action on it will brutalize soft brass cases to the point it will eventually stop the gun from functioning outright, this causes a side effect where, since even softer steels are much harder and less malleable than brass, they don't conform to the chamber as tightly when fired so, as a result some residue will slip by, it wouldn't shock me if the same issues applied to Chinese steel cased ammo but I'm not sure how hard it is compared to French Steel intended for the FAMAS. But, to answer a question you may have on the difference between why it's used, it's simply because steel is cheaper than brass by a significant margin, hell, the US Armed Forces have looked into steel casings several times for the same reason and I think still are but it's never gone anywhere, @Sturgeon knows more about the various US steel cased drives than I do. (note the DBP10 appears on the outside to be copper, but it's simply washed in copper to feed and extract easier and is still steel underneath, same concept behind why most high end defensive ammunition in the US is brass plated with Nickel.) "How about tracers for machine gun use? For example, the US issues belts of 200 rounds (four rounds of M855 ball/one round M856 tracer/M27 link) for its SAW. Is there a Chinese equivalent?" They use the same 4-1 ratio that the US Armed Forces do for tracers.

Tiamat was originally a Goddess and later a massive serpent that represented the chaos of all creation, but not really a "demon" per say.

"does it have a penetrator (ala SS109)?" Yes, every single round since the original DBP87 with the exception of some concept match grade round named DBU141 has a hard cast lead over hardened tool steel core. It's shorter in the DBP87/95 but very long in the DVP88 and DBP10. And the odd man out. The middle one is actually DBP95, however the only actual differences between DBP87 and 95 are the the powder used (It's burns cleaner) and the primer. (from corrosive to non corrosive) so it's a very small change. "What’s its BC?" for which rounds exactly? either way I'll have to give rough calculations on some unless another member already has them. "Is there an AP variant?" yes, DVC12, 85gr projectile with a hollow tip and a 54gr Tungsten core with a small lead ball between the tip and the nose to act as a "cap" and keep it stable in flight, appears to use the same very thick, hard H90 alloy jacket as DBP10.

"Something better." So....anything?

This was announced a while ago actually. Kind of sad, Remington used to actually have a pretty stellar reputation in the industry, then Freedom Group came along.

Keep in mind a lot of outdoor ranges or private places like farms will get bitchy if they see you using tracers due to the fire hazard risk. (yes, tracers do, infact, burn hot and long enough to ignite certain materials.) I have on at least one occasion started a brush fire unwittingly firing off a mag of tracers during the winter, was a dumb thing to do that I didn't take into account.

That's impossible, you're literally asking Reddit users to use tools they straight up don't have. Just don't worry about them, you actually have an audience here (and people who read here who will spread it) that actually have to ability to think.

I remember that, Sun_Leader or something like that right?

Well being that both hardcore WT/WoT forum posters and pretty much all of Reddit in general (not just the WT section) have a pretty big reputation of being home to some of the biggest autistic basement dwelling horsefuckers on the English speaking web, I wouldn't worry to much about being attacked here by that demographic. Also thanks for more writings. Funnily enough, it was never really Waffentrager that bothered me though, It was the fact he was too connected to Daigensui/Sumeragi that always raised questions though. (if you need to ask who that is, spare yourself the mental agony of finding out.)

PICTURE WAS OF HACKED BY COUNTER PUTIN TROLL FORCE.

That's 70 years in DOG years.

Come to think of it, I was thinking about this. Was the Sterling SMG family the last good indigenous UK gun design before their small arms design ability turned to India level or am I missing any?

@Sturgeon You have a good eye by the way, I went back today after reading up on them and it is infact a pre import model, apparently the guy who owned it sold it because he was near bankruptcy and unfortunately just had to sell a lot of shit according to the story. Even before he told me it was rated at 90% condition, I would've easily believed him as I looked it over beforehand and It's in beautiful shape. TLDR: I now have an RPK clone I guess, kind of wish it was an RPK-74M clone but hey, what can you do?

You forgot the STAFF. .....5th times a charm maybe possibly?
