Would just like to point out that the Federov Avtomat was not chambered in 8 mm Mauser (7.92 German) but was actually chambered in 6.5 Arisaka (Japan).
probably should be in the bug report section
I mean not exactly a bug, just an incorrect fact on a weapon. Doesn’t affect gameplay in any way.
bugs do not have to be related to gameplay. A bug is anything that is incorrect/unintended errors
The stg44 dont use 8mm mauser either
I’m no dev, but I’d bet this was a temporary re-use of assets for testing purposes, and we’ll see the proper 8mm Kurz and 6.5 Arisaka designations in future tests/on release.
It has nothing to do with re-using assets as it is simply a text file that gets displayed on the screen. It’s more likely to be a copy-pasta error than anything 
Again, I’m no dev, and have very little experience with coding, but there could be shortcuts in place. Say, make entries for ammo and magazines first, just the basic ones you need to get the job done, then tie displayed ammo type and magazine used/model to the ammo entries. That’s what I was thinking, but you’re still right, unless the models and data for 6.5 arisaka and 8mm kurz, as well as federov and STG magazines as individual items don’t exist, it should be as easy as editing text.
