Went to the range yesterday to sight in Nancy's Finn VKT M39,
Noticed that the gun was piercing primers using PPU 182 gr FMJ ammo.
Used the Russian field gauge and the pin was between the low and high slots. Seemed to check out. The armorer's markings on the cocking piece aligned also. I'm wondering if the cocking piece was a replacement part (non arsenalled?) or if I can simply file a little off the end of the pin. or is it the PPU Primers being too stiff? My other guns were running the ammo just fine.
Any thoughts or shared experiences with the ammo would be appreciated...
