KS47 and Surplus ammo

As the title states i have multiple 47 setups one being a WP47 LOWER and KS47 upper with multiple thousands of rounds i also have a WP47 complete gun. I have had ZERO issues with either platform aside from the PSA gas block walking loose my question is what has been your experience running SURPLUS AMMO with BERDAN primers like GOLDEN TIGER, RED ARMY, ETC? I run steel case all day no problem I can't for the life of me get the surplus stuff to run it'll run on ths second strike even with the PSA ENHANCED FIRING PIN, RTB ENHANCED FIRING PIN, WOLF EXTRA POWER SPRING with no luck. Is there a better pin or a trick you have found yet?
