Severe bullet setback with 357SIG ammunition.

[Airman193SOS]

It's been said that you should not unload and reload your weapons repeatedly because it may result in bullet setback. I haven't had that problem with my other autoloaders, but today I noticed that, for the second time, one of my 357SIG hollowpoints was pushed back into the case quite noticeably. I suppose that it's my fault, but I've also been lead to understand that this is quite common with 357SIG ammunition. It certainly is with what I have loaded.

In any event, keep your eyes open. It would suck to have your handgun blow up in your hand because of overpressure when it was something preventable.

For the record, I'm loaded with Remington Express 125-grain JHPs. You have no idea how hard it was to find those in the area without driving 45 minutes to the nearest dedicated gun shop. 357SIG just isn't very popular around Central PA, I guess.

I have 2 firearms in .357 Sig and have the same problem. One handgun is much worse in that case than the other.

It is often blamed on the very short neck which makes it hard to securely hold the bullet in place.

Thanks for the warning and, yes, it is common.

Thanks for the warning. My Glock 33 will be coming home in a few days and thats good to know.

bullet setback

I have heard the same thing from several people and I have been keeping
watch on that also. I guess I have been lucky, I have been carrying a
Glock 33 for 2 years now and haven't ran into any problems yet. I might be
getting lucky because I carry golden saber bonded ammo. and it might be
holding better who knows just a guess. Thanks for the reminder though, a
mind needs to be refreshed every now and then.

So I ran a little test. The crimp on these is so weak that I took a NIB round and squeezed it. The bullet settled almost all the way in with an audible pop. I didn't even have to squeeze terribly hard.

May I suggest that you guys avoid buying Remington Express JHPs for the 357SIG?

I load

With Bluedot or AA#9 but any powder that is slow enough to fill the case will help. You will need to check it for flash at night. I also would only do the same round 2 times then put it in a pile to be shot. If you can do it. I lowered the slide slow and did not get any setback. Do it wrong and you might shoot yourself,

Thanks,Keith

Having reloaded ammunition for many years I can only say that ammo that sets back upon loading is defective due to poor quality control and insufficient product testing. With proper case neck tension this cannot happen. I would let the manufacturer know that they have a serious problem.
