If you are loading .40 S&W (this calibre seems to be prone to these issues, but likely not the only one that is) there are a number of things to look out for if you are using once-fired or range brass:

1. Battle of The Bulge

.40 S&W fired through Glocks (notably, but my Beretta 96 does it too) can result in a bulge or "Glock Smile" at the base of the fired brass near the web. This is due to the feed ramp protruding well into the chamber of the barrel resulting in an unsupported area of the brass casing above the web. Often, sizing dies will not go down far enough on the brass during reloading to take the bulge out. If left, the bulge will result in stuck rounds in the barrel, FTE's, or out-of-battery conditions during firing. The dirtier the gun, the worse this gets. There are two relatively cheap ways of handling this issue. The first is using a Lee Bulge Buster kit along with a Lee Factory Crimp die of the appropriate calibre to process your brass prior to loading. This does a great job and all rounds will chamber perfectly. The second, if you happen to have loaded rounds that are bulged in some way, you can use a Lee Factory Crimp Die in a single stage press or as a final step in a progressive press. This also ensures the rounds will chamber perfectly. The first method is preferred over the second as you are not working with loaded rounds.

2. Watch your OAL

.40 S&W seems, in my experience, to be far more finicky than 9mm (or .357, or 5.56) to load and be consistent. Very small changes in OAL can result in FTF's in a a wide variety of firearms, so if that is your problem I would look here first. I stay between 1.125 and 1.135 inches and that seems to work just fine. Anything shorter is a crap shoot for my aging Beretta. Yours might be different, but that's my experience.

3. Check your brass

.40 S&W also seems to react to pressure over time sooner than other calbres I have reloaded. This could easily be brass quality as I am shooting mixed head stamp, but I have not noted cracked brass showing one particular head stamp. Brass will thin and crack at either the top (vertical split) or at the top of the web (Glock Smile location discussed earlier). Check all your .40 brass and stay safe.

Other things I have learned about reloading:

1. Take your time. If you are in a hurry, go buy some factory and shoot that.
2. The RCBS Lockout die is worth it's weight in gold and should be on every progressive press in the nation.
3. Double check everything, all the time.
4. Don't cheap out on equipment. You'll be sorry you did and you'll just pay in other ways.
5. If you are not at least somewhat detail-oriented, don't reload. It's not for the impatient.
6. Play around. Seeing the effect of small changes at the press on the range is a part of the fun of reloading.
7. Don't go straight to max load. Start midrange and work up. Your shooting hand will thank you for the lower recoil and you won't turn your $1500 Kimber into a hand grenade.
8. The Lee Factory Crimp Die is probably the best crimping die on the planet.
9. Load in a well-lit area.
10. Wear safety glasses and latex gloves.
11. There are regulations that apply to the storage of powder and primers. Know them and act accordingly.
12. If in doubt, pull and start over, even if it means pulling 500 rounds.

I'm sure there are other nuggets others can add, but these are mine.

Another product similar to the Lee Bulge Buster is the Redding G-Rx.
If you will be reloading large volumes of .40 you can buy a rollsizer such as the one made by Casepro or Scharch.
 
I have a casepro 100 on a custom dc auto drive. It does a great job with base resizing. If any brass truly shows the glock smile I highly recommend scrapping it. You normally only see it in brass fired in Gen 1 glocks. There aren't many around in law enforcement circles anymore. As they are the primary consumers of 40sw. At least in Ontario.

No such thing. The 40's didn't come out until Gen2 .

Thank you for the info. It's very helpful since I bought 2000 pieces of .40 S&W range brass. I would say that maybe 20% of it so far has needed the G-Rx treatment. (about 200 of 1000 pieces) I ran all of it through anyway just because it seemed easier to just get into a routine with my Rock Chucker.

Thanks for the other tips as I am getting close to doing the rest of the loading and testing. Mine will all be shot with a G20 that has a Lone Wolf barrel. It shouldn't have as much "smile" since that barrel has a little more support.
 
I have purposely taken 40 S&W brass that I picked up at the range with very obvious Glock bulges and resized them with my RCBS carbide die and it took care of the bulge no problem. I'm not sure why special dies are needed, is it just a marketing ploy to sell more dies?
 
It mores comes into play when you are using competition grade pistols (svi, sti 2011 format...etc) that have tight chambers. If the brass was originally fired from a duty pistol with a loose chamber. You would still only get a small percentage of rejects if you didn't perform any form of base resizing

Well, I'm not affiliated with any reloading company and so have no interest in selling additional dies (or encouraging any added expense to the process, since that is one of the primary reasons for reloading in the first place). I can get rid of the bulge if I crank my Hornady sizing die down just perfectly as well. But even so, I find a more consistent chambering after sending them through the Lee FCD. It was cheap ($32 at my local gun store, probably cheaper online), quick, and effective. I'd encourage you to borrow one from a friend if you can, and see if it makes a difference in the final quality of your reloads.

I have never had a problem with any of my 40 S&W reloads and I use them in two different pistols, the concept of resizing reloaded ammo seems redundant to me. If you need to post reload resize I would look at you reloading set up because something isn't correct.
 
I find the Lee FCD causes more problems than it solves. It swages my cast lead bullets down too much and increases leading in the barrels from the now under sized bullets.
