Sounds like guns are as hot and dirty as car engines. My lawnmower got stuck. So, I had to put more oil in it, for example. Now, I say that to say that engines, machines, and now, even guns, can get clogged up like an old heart artery. So, I've not got around to learning how to hunt yet, but I am beginning to understand some of it. So, I just never really thought about this before, well, until now.
