Setback

[WDE91]

I figured LEO's would have good experience with this if this is a problem

I was wondering if bullet setback is much on an issue for LEO's
The projectile receding back into the brass from constant chambering and unchambering

How often do most police handguns get unloaded?
Nightly
Weekly
randomly

Is it something that you found to be an issue with a particular loading?
Does police ammo have an extra tight crimp to combat setback?

I saw the issue here in this video which is what prompted the video

Never had an issue with setback.

About 85 - 90% of the guys I work with unload their firearms once every 4 months during our department qualifications. I usually shoot once a month but I never rechamber the same round so I have never had a problem with bullet setback or know of anyone who has had the problem.

A mostly non issue...

I usually left my duty gun in it's holster loaded and just hung my duty belt inside my locker after each shift.... I shot at least once a month so duty ammo was loaded and unloaded each time.. I was more concerned with the steel extractor damaging the rim of a cartridge due to repeated extraction and loading .... So I was sure to cycle different rounds to the tops of my mags when reloading them.

Actually I never noticed any significant rim damage or any bullet set back during 30 years....

We also shot out duty ammo once a year instead of the training stuff, so the duty ammo never got "stale".

Never experienced setback with a duty round, of course I never rechambered a round either. I'd just shoot the chambered round whenever I'd practice and we'd always greta a fresh loadout whenever we qualified.

When would you think we would unchamber and rechamber a duty round?

Thank you for this insight

I have never spent much time around any LEO's, thus couldnt personally ask one, so this is the second

Ok so it sounds like this isnt much of an issue

I am wondering if the guy in video kept cycling the round thus leading to the issu

It does with my off duty weapon... xdm 3.8 with 9mm corbons.

Not LEO,

But as a security professional I've carried the same ammo for months. And shot off the chamber'd round no issues at the range. I mean if your taking out the ammo out of the magazines and occasionally drop a round on the floor and put it back into the mag, then maybe you would have issue. It all depends on how you store it. I mean my carry ammo isn't usually shot off which would be Speer gold dots, so I wouldn't know if I had a issue unless I had to use it. Range ammo is usually new ammo for qual's.

But then again I heard a story of a WW2 P-38 plane being pulled from the North Pole. And all the ammo linked still fired in a machine gun they recovered...

We'll old ammo/the bullet removing reward. It's still rare, and will usually go boom I don't think the case rupturing is going to happen in 9/10 times, but visibly you should be able to tell the difference compared to a property seated round.

And your welcome for the vid.

[Ron-Solo]

Never had an issue

[tyrist]

Gun is only unloaded for cleaning every few weeks and the ammo is completely changed out every 6 months. Never seen a round suffer from bullet setback.

I think setback only tends to be a problem for those that feel the need to constantly load/unload their carry gun. I know a couple of guys that load/unload multiple times a day.

Generally I think carry guns should only get unloaded for shooting or cleaning/inspection and that's it.
