Leaving the Glock loaded--yes, that's the gun in question since it is my loaded HD pistol-- is not a solution. The gun gets unloaded when it gets taken to the range, which means the previously chambered round gets ejected. I've been diligent about not re-using these rounds, so now I've got a little herd of them (well, a dozen or so) in an MTM box marked "Don't Shoot."
No cartridges are going to suffer setback from one chambering. They get thrown around both in the magazine during recoil and during normal cycling. If you're worried instead of unloading the chambered round at the range why not just shoot it? Or is that not an option at your range?
