Ammo Round rotation

[HDoc]

I know this has been addressed before but I can't remember the board consensus.
For my night stand gun which has a round in the chamber, I've seen where
some folks rotate that round out on a regular basis. For that matter, some folks seem to rotate their EDC chamber round. Why?

[jocko]

If a person is a real die hard oiler of his gun then sitting with a round in the chamber over time "could
" cause seepage behind the primer cup, Some just feel to error on the side of caution and rotate it out of the chamber periodically.

I carry my PM9 loaded with defense ammo and I have tried to when going to the range at least every month to just shoot out that magazine and start with new fresh defense ammo. Never had one issue doing that but clears my mind over the "if" part. Probably not necessary but also gives me the chance periodicaly to feel the difference in a defense "hotter" round than my range fodder wwb .

I think it is an individual choice more than anything. Oil and some of our lubricants today seem to be able to pentrate areas that years ago could not be done.. another reason for this ol timer anyhow to want to kee his striker channel dry and clean..

In addition to what Jocko just said many rotate that chambered round after it has been chambered a few times in case there is any bullet set back or deformation during the chambering process.
Some say factory ammo won't set back but depending on the gun and what the round has to do to chamber it can happen. I've seen it.

A visual comparison to the remaining rounds usually will tell if there is set back and it would have to be set back noticeably before it would be a dangerous over pressure situation.

If your guns just setting in the nightstand and not loaded and unloaded, just keep the chamber relatively clean and dry and I'd not worry about it.

good point, I would not want to unchamber and rechamber the same round many times, as set back probably will occur. Once or twice might get u by, but I guess my question woulds be WHY

Thanks for the answer. My thoughts were deformation and seepage also, but I keep the gun lightly lubed until I leave for the range and I don't reload the chamber with the same round, so I'm thinking I'll just let well enough alone.

I wouldn't worry about it.

With premium ammo, I don't think it is an issue. I went through a testing phase a while back. I chambered and unchambered a single round many many times. I measured with the calipers, no setback.

I tried to make the primer fail on some other ammo with oil. I was unable to make it happen with loaded ammo.

So I think you could get away with out changing the round for a very long time. For me, I decided that I will shoot at least one mag of premium ammo a year, because it makes me feel good.

I rotate guns I carry and don't like to leave loaded guns around the house in case of a break-in. If I should catch them in the act, I want to be the only one with a loaded gun. I realize they could bring their own Hi-Point or whatever, but why set myself up for a surprise.

I also like to dry fire.

Defense loads usually get fired every two weeks.
