This ammo is corrosive but cleaning your guns should prevent any issues. This ammo is a very popular choice for owners of such rifles as the Mosin Nagant, PSL, Dragunov, etc.
In this video I test these rounds against Various thicknesses of mild steel up to 1.5" thick, AR500, Concrete, and more. Full data and analysis to follow soon.
Firearms used in this video are a Mosin Nagant and a Romanian PSL-54c, two of my favorite firearms. (No mosin's were hurt in the making of this video, they are rugged as hell and enjoy a little roughing up).
