75 years of hunting and at this moment I only recall 2. At age 13 I received a new .22 Mossberg semi-auto as a birthday gift. The only cleaning it got was a wet Hoppies on a string down the barrel. After a few hundred rounds I shot it and it went full auto and emptied out. Crud had built up in the chamber.
I owned a Hercules grade Iver Johnson 12ga double. On a turkey hunt as my son closed it with a turkey load in both barrels, it went off. Took it to a gunsmith and found that both firing pins were broken. Have no idea how that happened nor how that caused the misfire.


BE STRONG IN THE LORD, AND IN HIS MIGHTY POWER. ~ Ephesians 6:10

Socialism is a philosophy of failure,
the creed of ignorance,
and the gospel of envy,
its inherent virtue is the equal sharing of misery.
--Winston Churchill
