P95Carry, we're in total agrement;
or a dose of boiling water followed by a normal cleaning.
Mike Irwin, I'm afraid I must respectfully disagree with you regarding Hoppe's #9's effectivness on corrosive priming.
1. I'm pretty sure it DOES contain some water. I will grant you may be correct, BUT...
2. The label on MY bottle touts its effectivness on corrosive prining.
3. I have used it as my sole cleaning solvent for all my rifles and I have NEVER had an issue with rust, even after shooting a large amount of Paki surplus .303 and WWII Brit .303, Russian and Chinese 7.72x54R, 8mm Mauser and several other old military calibers. 20 years of impiric observation should count for
something.
And while NATO specs are for non-corr. Many non NATO countries made 7.62x51 using the same primers as their own ammo. There was some Czech ammo that came in a few years ago that was DEFINITLY corrosive, as a couple of my friends found out the hard way after the gas systems in ther SA rifles rusted up.
And I second the statement that Berdan priming does not automatically mean corrosive. I have a large quantity of South African .303 that is both Berdan and non-corr. WWII and eariler US military ammo is Both Boxer primed AND corrosive.
