And don't think you can get away with waiting to douche out your weapon after shooting corrosive ammo just because you are in a very dry and low humidity environment. I made that mistake here in the Phoenix area a number of years ago. I thought since we have nearly zero humidity, I could wait 12 hours before hosing out the gun with solvent. I WAS WRONG!!!! When I finally pulled the rifle out of the case 12 hours later to sit down and do the cleaning, there was already a light speckling of pink beginning to form in the bore and gas system. I know people who take a water bottle and douche out their weapon with that immediately, then follow up by hosing it out with blasts of WD40 or other water-displacing oil.
