Not sure why you're doing this every day. Take a long hard look and see if there's a good reason -- in general, there's nothing wrong with leaving your pistol loaded and in its holster, and putting the whole thing in whatever safe you were going to lock the gun or ammunition on. (At least I assume there's a safe involved, else it makes even less sense.)
But supposing you need to do this, put two things wherever you clear your gun: a bowl and a box of your carry ammo. Every night, eject the chambered round and drop it in the bowl; every morning, top off the magazine with a round from the box.
When the box is empty, get a new box, and shoot up the rounds from the bowl on your next range trip.
Some people feel like cycling each round through the action one time, as outlined above, is as much as you ought to, but some people might go two to five times. That isn't hard either:
When the box is empty, you add a tally mark to the box, and put the rounds from the bowl back in it. If the number of tally marks matches your limit of cyclings, swap the box out for a fresh one, and shoot the old box up on your next range trip.
I feel like if you're practicing as much as you ought to, it's perfectly reasonable to shoot up once-cycled rounds at the range, but YMMV.>>39659623
Nah, as long as there's no visible bullet setback (and if you've been chamber-loading there isn't) it's fine, shoot it up at the range, just don't let them get that bad in the future.
It's generally better to load from mag. Some extractors are good to go snapping over chambered rounds, some really get beat up in a hurry doing that. OTOH, bullet setback is a thing, and more likely with mag loading than chamber loading -- but one or two extra chamberings aren't gonna cause a serious setback issue, it's more of a concern when you load and eject the same round every day for weeks or months.
