When all of your computer passwords are gun-related.
MosinNagant, K98Mauser, Springfield1903a3, etc. etc. I've used them all in the past.
Doing this is the BEST security where I work, because there are soooo many anti and lib types around, there is no way in he** they are going to figure out these passwords by guessing. hehe...
Aside from that, I love the smell of Hoppes #9, cosmoline, and the smoke from Remintgon .22lr shells after some rapid fire out of my Marlin Model 60.
