I'd like to start keeping my pistol loaded and ready to fire, because I'm realizing just how long it'd take me to be "ready to shoot" in the event of a home intrusion if I don't load the gun. Question is...if I want to take the gun to the range and I unload it/eject the round from the chamber, does the chambering and extraction damage the round in any way, or can it be safely re-chambered? Thanks |

Check the height of the round versus an un-chambered round. I noticed my Blazer 9x18 ammo would push the bullet further into the case, and after a few times of being vigorously chambered it would be noticeably shorter than the others. I started limiting the number of times I would chamber a round, and anything that has been chambered more than once gets checked against fresh rounds. |
+1 - It's known as bullet setback (or just setback). I remember reading about at least one case of setback in .40S&W with disastrous consequences (i.e., a kB!). Excessive rechambering of the same round resulted in the round being overpressure when it was fired - which is especially bad with something high-pressure to begin with, like .40. |
+1 bullet setbacks can become a problem and they usually arise from repeated chambering; also, re-chambering can cause excess rim wear which can potentially hinder extraction properly or simply cause bullet or case defomations simply: i'd rotate out once or twice chambered ammo at the range w/ fresh ammo everytime you re-chamber--cheap insurance for the most critical bullet (1st rnd) that you may have your life depend on |

I've always read that, especially with .40's, this can cause a kB. I put a little mark on the back of them when I take them from the chamber, and try not to chamber them more than three times. I don't know how bad the risk actually is, but I don't feel like testing it. |
