Interchaceable ammo, What Ammo type do we know that certan SR gun use. Options

[Dumori]

I reinstalled STALKER Shadows of Chernobyl and I have started modding the game when the idea of make the SR gun for the game and then using to SDK for it to begin work on a Shadowrun mod. But as STALKER uses real life ammo as in 19mm x 18mm round fit in all 19 x 18 weapon and so on. I want to know what ammo types we know or have worked out my searching has failed due to the number of way you could phrase this and how many topic it brings up so can any one be of any help. I know the perditor is 10x25 or 10x30 depending on the soruce. I will also need some comparison of these ammos and guns to some RL ones to help me give them stats but that is not as important.

Thanks Dumori

On a side not the AK97 wont need much graphical work as there is the AK 74 and AK 74 s/u basically the AK97 and AK97 carbine in the base game giving me some thing to work from.
