FWIW: A squirt of oil to fix an issue after it happens, should be the reminder to do your gun maintenance BEFORE you need it. The banded blackduck that’s flying away because of a gun malfunction, might be a sign. ....and yet, there’s probably just gonna be another thread n here blaming a gun for missed opportunities. ***I’m NOT saying don’t keep oil around. It’s always good to be prepared to address mechanical issues. Good oil, rags, and a Rapid Rod, will take care of most things that arise. Allowing your gun to sit around overnight, full of any concoction of water, mud, field debris, powder, etc, is idiotic.
