Well I used to leave the rifles loaded all season. Then when they started failing to fire on me, I changed my ways of doing things. I was always careful of how the rifle was prepared, how it was stored after the hunt, everything. I then started getting misfires. I can not depend on a rifle I am not positive with. Perhaps it is the climate I live in, or the weather I hunt in, but I shoot mine off at the end of the day, clean it, and reload it the next morning.
