The big question is why is it getting pushed back (setback)....???

werewolf,
Depending on the cartridge and type of load the answer could be no, or maybe.
Some cartridges have so little powder space that any bullet set back will increase pressure dramatically. Others not so much.
When I find ammo like that I use my bullet puller to pop them back out where they should be before I fire them.
Then as Cheesewhiz says, find out why they are getting set back and fix the problem.

The .40S&W is a small volume high pressure cartridge. I would be very careful. A kinetic bullet puller (hammer type) can fix that. 8) 8)

If this is just low powered target stuff, I would be less concerned.
...but many guys cycle and then cycle again their defense ammo and that's a no-no with an autoloader. If it's chambered once, that's it back to the bottom of the mag with that one. If you cycle defense ammo a lot, no matter the reason, shoot that stuff after one chambering, call it practice, call it smart. If you cycle your defense ammo enough and enough is no telling with your gun and ammo, it may not cycle reliablley again and that's not good.

Cheesewiz,I agree.I only use pristine ammo when carrying.I was just going to use these for range work.I had no snap caps and had to play with it longer then I thought to get it straightened out.I don't mix calibers but I have boxes I put rounds that I won't use for carrying.Maybe I wasn't happy with them for some reason and delegated them for range work.I just wasn't sure about the setback issue.I'll give them to the guy I work with.Maybe he can dismantle them and use what he needs.

Some Law Enforcement Agencies that issue .40 S&W handguns have issued a policy stating that officers ARE REQUIRED TO rotate the top round in their magazine on a daily basis. Once that round has been chambered and not fired, it cannot be left in place as the first round in the mag, to be repeatedly chambered (and not fired). Their reasoning is that some .40 S&W pistols are prone to cause setback of the bullet when a round is repeatedly chambered, which can cause higher-than-normal chamber pressure.
I don't know what type(s) of pistols this applies to, but it would cause me to think twice about firing a .40S&W round like you mention. Be safe - either discard the round(s) so affected, or pull the bullet(s) and reseat.

Setback = bad.
Do not fire.
Do not discard; use a puller and retrieve the components.
