Here and in other forums I've seen folks recommend against chambering a round multiple times since it can cause it to recess into the cartridge and possibly result in over-pressure, under-pressure or something else bad. While I don't have an abundance of experience carrying, I've never noticed such an effect. Retired from the Marine Corps a few years ago, and pretty much every round I ever chambered was fired relatively soon afterward, so I never heard of this issue before.
Earlier this year I began carrying a 1911 and shooting 50-100 rounds of WWB almost every week. Defensive ammo is Winchester PDX1. So at least once a week I drop the magazine, eject the round and replace at the top of the magazine. (I don't do +1, mostly so I don't have to find another place for the extra round when unloading for practice.) I have two other magazines I use for practice. After about 300 rounds or so of WWB, I fired a whole magazine of PDX1, no problems at all. About every 4 - 6 weeks I fire off the first two rounds of my defensive magazine, mostly to make sure everything works, but also because I want to keep a fresh round in the chamber. If I remove the defensive rounds for some reason, I keep them in sequence so the frequently chambered round is always the next to re-chamber and be fired.
Now, the question: What experiences can other shooters share in this regard? Not really looking for what others may have heard or read elsewhere (unless it's particularly interesting), but what can you tell me from first-hand experience?
My defensive ammo has fired every time so far, so I don't see the need to change my practice. But since my life may one day depend on the round in the chamber, I would give weight to advice based on experience (as opposed to hearsay). Thanks,
