Insurance against what? You could take those rounds and compare the OAL to a new one. If there is no setback, why discard it?

I don't notice 'set back' as much with 9mm and .45acp as I notice with .357sig, so I don't rotate as much as some do. However, my pistol is always loaded until I go to the range.

I do notice the casings getting dinged up on the rims with loading and unloading. A little 400 grit sandpaper on the sharp inside edges of my magazines cured that.

Read DMF's Oct 12 post. One takeaway:

This caused an internal failure of the primer, not discernable by external inspection.

I shoot my carry magazine 2-4 times a year, depending on the firearm's use.

Mag in the weapon gets fired (sometimes the reload too), then the reload goes in the pistol and the reload gets new ammo (or they both get new ammo if I shot the reload as well).

I don't have an issue reloading a single round several times, but I wouldn't do it often or for months on end. Part of the reason I have a training G19 and a carry G19. The carry gun is vetted and solid, but stays loaded. The training gun gets used for dry fire, live fire, drills, etc.

And know that any gun, any magazine, any ammunition can fail at anytime. New, used, abused. Unseen manufacturers defect or known neglect. Be ready for that and be able to work through it.

Because even in DMFs example, all other 2000 rounds fired and the failure was likely due to HUNDREDS of chamberings, not 1, or 2, or 10.

I want to thank DMF for posting that link.
I had not thought of the failure mode that was found by the ammo manufacturer. I was solely looking for set back and other external mechanical damage. This exchange sums it up for me now:

While the overall probability of a failure is likely very low, I was at higher risk with my EDC because I would rechamber one round from a six round mag at least weekly and would only change out the ammo 2 times per year. I am definitely changing my protocol.
