I agree, spraying the Mosin works very well (and looks goddamn sexy ;) ). That thing with the Rabbits: I noticed (playing together with my friends) that only you can see that one specific Rabbit running just across your way. I guess those Sounds (eating, reloading, etc.) are some kind of Bug, that happened to us (no i dont mean mysekf, but my friends an me), where random Sounds played at some Locations. But if you listen closely, youll notice that those sounds are interrupted and just a part of that normal sound.
