I haven't tried this extensively, but from what I have experienced so far, the mosin seems to be really weak in experimental. I shot a dude with a Press vest with the mosin from maybe 50 metres and he just tanked it - took a second shot to knock him uncon, and then I still had to finish him on the ground. I also had another incident where I shot a dude square in the back from maybe 30-40 metres, he was wearing a plate carrier, and he tanked it and carried on running around like nothing had happened.

Not sure if this is intended or not - I also realise that I haven't had enough situations to state this with absolute certainty, but the mosin seems about as strong as a pioneer. I may be mistaken though.
