Is there an accepted date cutoff of corrosive x54R.??? I have heard 1957-58 for most every western country...... I know countries in Asia made it much later.

I shot 4 different x54Rs recently and left the booster sit on the bench to see what would happen......one week later, nothing.

You probably had the booster so oiled up nothing can get through!

I treat all surplus 54r as corrosive. Maybe new made wolf and the like are not but all others are. Even if mildly so.

there is no "non-corrosive" primer in any east bloc ammo at any year, they all have fulminated mercury primers ( corrosive primer). because of their long shelf life in storage.

rust develops due to how high the humidity is, in low humidity not so much, then in higher humidity. the salts acts as a sponge

it not hard to rid yourself of the corrosive primer salts , just scrub it with hot water and flush it out, water is the best solvent for dissolving corrosive primer salts, then dry and lube

or, just shoot commercial x54r if you want "non-corrosive" ammo
