Concerning Soviet surplus 54R with the steel case, as well as current Wolf Extra Match which IIRC has a bi-metal case:
Will regular shooting of these types of ammunition gradually degrade the accuracy of my Mosins?
Right now I am sticking with new production Prvi and S & B ammo, as these have brass cases + copper jackets, but I have a lot of surplus and would like to shoot it.
Thanking you in advance for any guidance...
