The Zone of Alienation mod is an adaptation of the renowned AMK mod. It is built on top of a specialized variant of AMK that uses a magazine system. From this premise, it has expanded to aim to include the following:
Left to right:
7.62x39 HP - WPA Wolf Military classic hollowpoint.
7.62x39 M67 FMJ - M67 Yugo round.
7.62x39 SP - Soft Point expanding ammo, Silver Bear.
7.62x39 M43 FMJ - Older Soviet-styled FMJ.
Cool stuff here, you might use some Wiki information to help with designations as well. It mentions the "7.62 PS" which was the one that passed GRAU testing and was adopted under index "57-N-231S" (later final S was omitted to generalize all 7.62x39 cartridges in Soviet service regardless of build). I guess the Russian M43 cartridges are actually the 57-N-231.
There's also a weak AP cartridge developed in 1980s/90s named BP (GRAU designation 7N23, black-tipped AFAIK).
That is correct, the official designation of the cartridge is 7.62 PS (57-N-231), I used the informal name of the model year to differentiate it from M67, which does more damage and is slightly more accurate.
Most of my names and descriptions are placeholders, so I can definitely change it.
Oh yeah, and I'm not adding AP for 7.62x39 either.
