about shelf life. In 2006 I was seeing ammo start to go up in price sharply. So, I was running around to the retail stores and buying up all the 45 Colt and 9mm ammo I could at about $15-$17 and $7 a box respectively. Now I am sitting on over 1500 rounds of 45 Colt and about half that much of 9mm. So, since I do not shoot up ammo rapidly I am wondering how long this will keep without significant deterioration. Thanks in advance for sharing your knowledge with me.
