Re Chambering a Round

[gunflint]

I have changed my carry gun from my trusty revolver to my 24/7 Pro 40. I could use some advice on re chambering rounds. I like to do a lot of dry firing particularly now that range time will be reduced to around zero until spring. Anyway, is it dumb to re chamber a round a couple of times? I've read that it is and it isn't. I was planning on rotating the rounds in the magazine so I didn't end up re chambering the same round many times. Any thoughts?

While Pinnacle is the resident expert (note: heavy on the "pert"), I have noticed that repeatedly rechambering a round will actually push the bullet deeper into the casing. This could cause an over-pressure situation. A KABOOM! could really mess up a guy's afternoon...

Also, at least with my 1911's, repeated rechamberings will start to chew the case rim. If this is carry ammo, an FTE at the wrong moment could also mess up an afternoon.

Simple ..........shoot the round and replace.

Just the round, or possibly more...?

[ttousi]

or the entire mag............need to do that periodically

That's what I've been doing but with snow on the way I won't be doing much shooting except to try out some recipes before going into major production. That's why I'd like to eject the chambered SD round once a week or so and dry fire a hundred or so times over the evening. Would it be that bad if I rotated rounds so that the same round wouldn't get chambered more than twice?

I do chamber the same round multiple times. BUT I do also measure them to make sure they haven't changed length. I have yet to have my carry ammo (HST) have bullet setback.

Same here, but with Cor-Bon 9mm.

Same three with GD/HST/hydra-shocks in .40

Just don't slam the slide shut on the round.

Since at least one of your concerns is re-chambering the same round over and over, consider snap-caps. These are dummy rounds, usually in translucent red plastic, that are made to absorb both the repeated strike of the firing pin and the catching of the extractor claw.

You don't have to buy a whole magazine-full, just a few. there are online sources, but I've seen them for less at GunStop out in Minnetonka: 952 474-0211, where you'd be supporting a local business, which is always good, in my opinion.

I just compared Gunstop's price to an online supplier, and they're about $3 less for a 5-pack at Gunstop.

I usually don't rechamber, I just burn the mag and spares just to exercise the weapon, magazines, and ammo at least every 30-45 days.............

This way I get to buy "fresh" monthly, as I dreamed that I read somewhere once upon a time that when you open a box of ammo that it starts diminishing its power and effectiveness after 60 days.................

I've been running an experiment. I've been loading and unloading the round on the left everyday for the past 8 months or so. As you can see the bullet hasen't set back, but unfortunately, the HP is almost entirely closed.

What kinda gun are you using?

[Rip Van Winkle]

What kinda gun are you using?

Colt Govt. model, series 70.

Funny... My 1911 chews up the ammo pretty badly, and also sets the bullet back into the case a noticeable distance. Maybe it's the Golden Sabers I'm using?

Since the local ranges won't allow steel cased ammo, I usually end up just throwing it away after awhile.
