OH NO!! _ Rust!
Due to serious health issues that are still ongoing, I hadn't looked at my Pursuit LT since I last cleaned/oiled it and put it away last October. Yesterday was 1 of the few days lately where I felt pretty good so I decided to pull it out of the gun safe. Grabbed the wrench and gave the breech plug a turn (it moved a bit stiff at the start), and unscrewed it. First thing I thought was, man it seems dry, I'm sure I lubed it well before putting it away. Then I took a closer look - a slight brownish tinge on about 1/2 of the threads. Rust!! I looked down the barrel and it looked like it needed a cleaning. To make a long story short, the rust was minimal. But - I would have swore with the cleaning I gave it last Fall that there was no way I would have had to worry about such a thing.
In my opinion it just shows the importance of checking on stored firearms on a regular basis, particularly muzzleoaders.
