Ok. I just recently bought my Kar98. But I want to use it as a hunting rifle, and a plinking rifle. But in some situations I wouldnt be able to clean the rifle after I have shot it (while Id be huntin [and using corrosive ammo]). Or atleast I wouldnt be able to clean it for a long time; after I shot it. What do I need to do to my Kar98 after Ive shot it? And I cant clean it? Also, how long after you fire corrosive ammo through it does the corrosion start to set in?
