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 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.... "rlol"

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?

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.

I don't recall who made the video, but there is a video on youtube about KB's from bullet setback, said individual took a hammer to the end of the bullet and caused very noticeable setback and fired quite a few rounds like this. I believe it was a 40 s&w glock

Press check is a reliable and safe method of verifying the condition of the gun. No need for "mirror and flashlight" tricks. :lol:

Press checks are one of the more enjoyable routines a person does to ensure they are ready. In the case of revolvers, opening the cylinder and closing is appropriate too.

This thread is another reason I like to hang-out here and mill around. As a newbie to semi-auto firearms I had to look-up "press check" and "bullet setback". I'm gonna practice the press check, and I'm also going to pay close attention to the fit of a bullet to a casing as I load & unload.

Thanks folks.

eject the magazine, ejecting round, cycling slide a few times to make sure nothing else in the chamber, lock slide, visually check chamber, insert magazine, slide release to chamber new round,safety on, release magazine, thumb out couple of rounds, load ejected round into mag along with other rounds, insert mag, double check making sure safety is on.

The press-check for semi-autos has been standard practice for decades. Grip the pistol with your offhand. Use your dominant hand to grasp the slide and move it a few millimeters backward. Check the chamber and release the slide.

You have secured the slide and successfully performed a press-check.

Not a bad idea, but I still press check every time. Not that I ever unload the my main carry gun but still...
