Since I have not been shooting for a couple of months I started wondering what would be the best way to store an air rifle. Should you empty the air reservoir? Would that cause some deformation in the orings? Would it be best to keep about 50 bar in the reservoir? I have had them stored away for about two months now with 100 bar in the reservoir and no problems. They do hold the pressure pretty well. They are both Cricket Bullpups in 22 and 25 cals.
