I use the 5x5 Gamo and Air Venturi targets in my pellet trap. I started shooting pistols more with wad cutters. Because I live in an area of high humidity 99% at 5 am tomorrow my targets get soggy after I remove the plastic. The pellets cut perfect punch holes when I open the pack. But after a week they rip.Should I store them in the freezer or get some sort of cigar box to keep my targets at the perfect moisture content?
