How often should I be changing out carry ammo?

I dry fire and practice my draw daily which means I have to unchamber and rechamber often. I've gotten into the habit of swapping the chambered round out to the bottom of the magazine at the end of every week and so far haven't noticed any set-back at all. So I'm wondering, should I keep this going until I notice set-back or should I change out the whole magazine after I loop back around? via /r/CCW https://ift.tt/3jDRS8l
