.40 Range Brass Gets a Real Good Gouge in Resize Die

It's hard to see how damaged they are but generally if in doubt, chuck it. Damaged brass can lead to mis-feeding and you also have to wonder why the sizing die damaged that particular shell casing (excessively bulged perhaps). Not worth worrying about.

Shooting a Glock? Looks like Glock bulge!
I have a four year old Glock 22 .40 and do not have a bulge problem, the majority of firearm manufactures fixed this problem with redesigned feed ramps that support the base of the case better. Also the ammunition manufactures started making the base of the case thicker and harder to help prevent the bulge.
If you are picking up range brass fired in someone else's .40 S&W you need to be more selective on what you keep or else buy the Redding die below that will return the case to minimum SAAMI dimensions.

"The Redding G-Rx Base Sizing Die meets the need of the reloader needing to reload brass shot through some of the most popular autoloaders today. These autoloaders, when fired, produce a bulge at the bottom of the brass, which normal sizing dies can not reach and remove, rendering the brass unusable. Simply push the brass through the sizing die and the bulge in the web of the brass is removed. This step fully sizes the brass back within the accepted SAAMI specification for brass diameter. After the brass has been pushed through the die it may be resized in a standard sizing die allowing once unusable brass to be reloaded normally."
Below is the fix Glock made to their barrels to stop the Glock bulge. People who do not reload do not care about Glock bulge, people who reload send their pistols back to the manufactures and have a new barrel fitted.
The .40 S&W is not a magnum and for practice you do "NOT" need to load to maximum levels. Below .40 Lite loads with Rainier plated bullets.

can't tell from the picture as it's so dirty and you didn't clean before decap. in case it's anything like in my case: http://www.canadiangunnutz.com/forum/showthread.php/1288856-LEE-sizing-die-defected-out-of-box/page3
could you please measure the case with caliper like what's shown in my picture? obviously in my case, the sizing die would size the top smaller than it was which made the case appeared to be "Gouged"/"Glocked", but it's not, especially if it's was straight, but "bulged" AFTER it went through your die. read through my whole post and you will see if it's the same as in your case.

Saw a couple like this tonight after the resize/decap die.
Should they be tossed?

The line showing up in the shiny part of the brass loos like a case head seperation in waiting.
Bulge buster before resize.

Looking at how badly marked up the rim is (and I can only clearly see about 1/3 of it) I would say that case has seen many, many reloadings which probably explains the case head swelling. 40 S&W is cheap and plentiful. When cases get this bad they should go in the recycling bin.

When the odd case like this goes through the die the relaxing flow of resizing is rudely interrupted. Way too much force required on the handle compared to the others. I appreciate the feedback here. Any cases that needed the extra force have been disposed of.

I agree with ted-dent: looking at the rim and web area of this particular case, there is a lot of extractor marking. Toss it - there is no sense in endangering yourself or you rangemates for the sake of a few cases.

1) When in doubt; toss it.
2) Do you use case lube?
3) Does the shiny worked area go all the way around or is it just around part of it?
4) It looks like the die is cutting into the brass- I've never seen a properly centered and clean die cut into a clean lubed 40 case "Glock bulge" -they just iron them out as much as possible.
5) The bulge buster kit in this caliber really works well- I use it on new to me brass.
