................But its probably there. I might be paranoid but i worry about how many times a round gets chambered over time and when it's best to shoot it off. I know guys who say 2-3 times and i know guys that tell me i am a freak for worrying about it. I carry an XD-40 on my hip at work, my partner carries a Sig P226 40S&W. We split a box of Powerball and don't keep track of which bullet gets chambered each day. We empty our mags every night and load first thing in the morning. Is there something we should be doing different? When should I replace our ammo? sorry if this is the fifth time today this is brought up....
