Maintenance Protocols Flashcards

Which type of ammunition requires especially prompt cleaning due to corrosive priming?

Corrosive primers leave salts that attract moisture and rapidly rust the bore unless neutralized and cleaned soon after firing.

What is the generally recommended method to remove salts left by corrosive primers?

Answer: Water-based cleaning followed by thorough drying and oiling

The salts are water-soluble, so water-based cleaning followed by drying and oiling is needed to remove them.

How often should a firearm in long-term storage be inspected?
