Video confirming this issue, recorded by Silo Entertainment youtube channel few days ago.
Exactly in minute 04:40 One of his friends shoot less than 100m from Silo and nothing is heard.

I can't confirm the exact rifle that can't be heard in this video, seems that wasn't a Moisin 9130, but i personnally can confirm 100% sure this bug affects the mosin 9130. Only thing i don't have a personal video. But this video from Silo reflects the bug.
Also i can confirm the PC profile of this user is correct, Game version too.
