Additional Step to Ensure Loaded/Unloaded Status

[Dave2]

When I'm not lazy I release the mag and eject the round in the chamber if there is one. Then I reinsert the mag and chamber a round, eject the mag to put the previously ejected round back in, and rereinsert the mag back into the gun and holster.

If you're chambering the same two bullets over & over again, be very careful about bullet setback. I've heard some people say it only ever happens on reloaded rounds, but I've had it happen to me with some of my factory JHP bullets. (Thankfully it's something that I'm somewhat paranoid about, so I haven't been bit by it yet.)

I haven't seen any yet.

I think it was a bad batch or something when it was happening to me. For a while there it seemed like I could only a couple chamberings out of a round before it'd get setback (Corbon 9mm +p 115gr JHP, FWIW). I haven't experienced it at all in nearly a year, though, so I guess they got their issues ironed out.

The new Hornady Critical Duty rounds were explicitly designed with cannelured bullets in semi-auto rounds to prevent bullet setback.

Here are some pictures from a message thread discussing this topic at Ohioans For Concealed Carry.

The 4th from the left is set back and so is the one in the middle with the black line on it.



Here is an example of bullet setback with 35 thousandths difference of COAL.




When we hear of gun KABOOMS at the range, most of the time we really don't know what caused it. I'm convinced that bullet setback is the culprit more often than people think.

Sounds like a great excuse to buy another gun that has a loaded chamber indicator. Will try passing that excuse by the wife tonight....

I am new to concealed carry, and this site.

I have generally just opened the slide and felt for the bullet with my finger.

isn't that enough?

if it is loaded and i want it loaded i just pull it back a mm or so and see the brass.

are you doing this in the dark or something?

Always in the correct order: Remove magazine; rack to eject round; visually inspect chamber/barrel; replace magazine; rack to load one round; eject magazine and manually "top off"; replace magazine

Finger always off the trigger.

I have seen setback on factory JHP rounds as well. Always something to be mindful of...

Bullet setback isn't the only potential issue with repeated chambering and ejecting of the same round. The extractor will nick the case rim with each cycle and it's possible to reach the point where the round may not eject reliably. If you run your finger around a round that's been through several cycles, you'll easily feel the rim damage.

I put the rounds in my practice batch after about 5 cycles just to be sure. An FTE is a very bad thing after the first round in a firefight.

My PPS has a chamber "window" where I can look down from the top and see the back of the round chambered. It's quick and easy verification, but I've always wondered if I can see the chambered round, would there not be ignition gas escaping from that window thereby dropping the propulsion pressure? I don't know how it works, but it does!

I think the pressure seals the casing to the chamber until the bullet leaves the barrel.
