I have experienced it, but only with pistols that also have feed problems where the round is jammed into the feed ramp, barrel throat, etc. It can happen with as little as 2 or 3 attempts to chamber it.

If the pistol functions as it should, you may never experience it unless you do an exceptional amount of unloading & reloading.

If the OAL gets longer that’s ok because pressure goes down the more empty space is created in the case between the powder and projectile.

When the OAL gets shorter is when you get pressure spikes from compressing the powder or making less space between the powder and projectile......just for clarity.

If the bullet is against the lands you might it may or may not affect the accuracy but that’s it.

Worth a check though because auto loading pistol bullets generaly don’t use a roll crimp so it is easier to dislodge the projectile. A very slight taper crimp is used , reason being is that the casing moth shoulder is what comes to a rest in the chamber creating the head space spec so there needs to be a pronounced shoulder and a roll crimp would take that away

WOW!!! So glad that I read this thread, I have rotated my personal protection rounds in the house pistol a few times just to mess with it most days, took all 7 rounds out and here is the result!!! Blows my mind, thanks to you guys and the grace of God, it didn't blow my gun/hand!!! Thanks for all of y'all's useful knowledge!!!

Well, I'm glad you found/read this thread too! Drop them in the dud bucket next time you hit the range.

[texasman55]

No doubt! That will be tomorrow thankfully, gonna get some range time with my mother's new XDm to be sure that its what I want before buying mine, probably tomorrow as well. I will be sure to ditch the duds and invest in a new box of carry ammo...

I seldom see the need to remove a round from the chamber. Store your weapon in such a manner that unauthorized access is virtually impossible, and leave it fully loaded.

For me it's store it on my nightstand where I'll pick it up in the morning. But I do agree that the idea of chambering and re-chambering is pretty much a wasted step in my opinion. Unless you just don't have a way to keep to form curious hands anyway.
