I always unload my Thunderhawk every night. Our hunt is late November and it is generally bitter cold with 2 ft of snow. Hang and miss fires are common in this weather.
My partner NEVER unloaded his Limon. Last year he pulled a 50 yd broadside shot on a dandy bull due to a hang fire.
Not only did I get to give him **** all year, I also got to here him say, " you are right, I should reload every morning".
BTW, I shot that bull that afternoon...
