I have repeatedly had the case that my mosin LR scope sways around from side to side like mad. This seems to occur after a zombie attack has injured me and I fixed myself up with a rag / bandage. Today my green hoodie was also ruined, so it may have been a strong zombie attack. Then again I could swear I also had this once although I was certainly never injured.
I waited extra long to make sure this had nothing to do with stamina.
Crafted a splint and used it.
Scope movement is gentle again, holding breath causes it to almost stand still.
Made a video of my standard zoom as well as max zoom when holding breath, before and after re-examined it and realised it was a world of a difference.
