I used to store them clean, coating of oil or light gun grease, bolt closed, empty chamber, trigger pulled to release the pressure on the firing pin spring.
Now if the gun is frequently used, I use a snap cap in the chamber in addition to the other steps, to reduce the dry firing.
Later I thought, a closed bolt is under some significant mechanical pressure, and I wonder if the bolt is best not closed to eliminate the stress, but then that leaves the firing pin cocked and the spring under pressure. They usually come from the factory not closed.
So what's the best way to store a bolt gun that is best mechanically for the gun itself?
Thanks.
