(I haven't found any weapon thread? Is there any? Men need gunz!)
Oh, yeah, legendary Mosin rifle. It is something! I know there was a case a soviet soldier hit a plane by this rifle. It was locally called as "Three-Linear" (~1890-1910's), because its size is about three inches (during Russian Empire period the metrical system was the same as in Britain Empire).
Heck, I must buy it! To shoot some... thing with it is just amazing. The video by the Demolition Ranch about the rifle perfectly discovers its pros and cons. Just check it out.
