question about corrosive and non-corrosive ammunition?

Corrosive usually has salts in the primer or as an ingredient in the powder. Most mil-surp and older ammunition is corrosive but it's a good idea to think ALL mil-surp is corrosive. If not cleaned properly it can cause corrosion in the bore and could destory a barrel in a day. Regular solvent WILL NOT remove these salts, you have to use somthing water based or special solvents meant to remove this stuff. It's best to clean it as soon as you can after shooting when using corrosive ammo. Windex on wet patches works but I usually take really hot water and a turkey baster and blast hot watert down the bore a dozen or so times, run wet water patches and then a bunch of dry patches. More thoughough but I don't like to take a chance like that. Take apart the bolt and wash the parts with hot water. Do this before regular cleaning with solvent and be sure to dry the parts as much as possible off the bolt parts and oil when your done. It's also a good idea to check the gun after a couple days to look for rust spots in the barrel and on the bolt parts. Non-corrosive means it won't corrode your gun if you don't clean it right away. Chrome lined bores do have some resistance to the salts but it's still a good idea to clean with water.
