Corrosive Ammo

[ireload2]

I once ran a test on an old Mauser using Egyptian corrosive 8X57 ammo.
I fired 20 rounds of the ammo and then cleaned the bore very thoroughly with Hoppe's #9.
Within 3 days I cleaned it again and the bore had began rusting.
I cleaned again within another 3 days and there was more rust.
I finally cleaned with soapy hot water and oiled the bore. That finally stopped the rusting. I would say that only a water based cleaner is going to get the corrosive salts out.
