Reloading .40 S&W brass from stock glock bbl

Can this be done? I noticed that the cases that I have are bulged, they were factory loads to begin with. Can I reload them and fire them in the stock bbl again?

Thanks in advance!

Absolutely not! You are risking a catastrophic failure of immense proportions if that brass even gets near your reload bench! I recommend you box up all the .40S&W brass you have and ship it to me for proper disposal. Please include a postal money order for $25 for the hazmat disposal fees I will incur on your behalf.










Seriously though, there is zero problems reloading glock fired .40S&W brass. Just be sure to re-size it completely to the rim. Dillon dies are notorious for leaving this portion of the case unsized. Lee carbide dies, among others, will resize the case completely.

I have been reloading some .40 (and by some i mean very limited due to shortages in the area) and have not had any trouble in my g27. The cases usually clean right up with the sizer die but the more pronounced the bulge, the harder it is to re-size.

ok then, thanks. I am new to reloading, and didn't want to die or lose an eye. just noticed case bulge, which I have in my reloading reading found is a bad sign. I figured I would ask people who knew something about it!

Thanks so much!

How old is your gun? Glocks have a looser chamber then some guns (even in other calibers). Is it bulged on one side? Just larger then your used to seeing?

I shoot a lot (several hunderd a week) of 40 through my glocks. once I adjusted my dillion die all the way down it worked fine.

I've resized and reloaded a bunch of .40 brass with bulges without any issues. I check them visually and in a lyman cartridge gauge when I'm done loading them up. I have seen a few that had pretty big bulges though which I have tossed in the scrap bucket. I have two 5 gallon buckets of .40 brass though, so why take chances?

AFAIK, there was never much of an issue resizing .40 shot from glock barrels with dillon dies that were then re-fired in Glock barrels. The problem was re-firing dillon sized cases from glock barrels in tighter chambers like those from LWD or KKM.

Bob Howard - With properly adjusted dies you should be fine.

I agree, but would that get the case sized down closer to the rim of the case?

Dudley, if you're asking me and referring to the GRX die then, yes...that is the entire purpose of the GRX die or it's lesser known competitor, the "Gizmo". The Redding GRX is a "full-through" die. It uses an extended "push-rod" mounted in the shellholder slot that pushes the cases up, through and out the top of the die resizing the base as it goes.

You'll notice the die specifically for this on Grafs (probably others, too):

You'll have to determine which brass deformations are too great and cull bad brass at your own judgement.

Look this is really simple, get a die that re-sizes all the way down - Lee. These push-through dies are to compensate for dies with too great a flare at the base. The flare makes it nice and easy to use, especially on a progressive press, but that wont matter much when your ammo wont chamber in your match barrel.

This guy is worried about safety and you guys are arguing about dies.

Because the die's are the solution to his safety concerns.

All brass bulges when fired, that's why cases must be resized. Unless some are severely bulged (especially, at the feed ramp position on one side), you'll be just fine. A concentric bulging of the middle part of the case is no issue and normal sizing dies should do an adequate job. Always make it a practice to run loaded rounds through either a case gauge or do a barrel test...whichever, is tightest.

Good point and talking about "bulged brass" as a generalization IMO, serves no purpose. There's "bulged" brass and then, there's "BULGED" brass. If it's "guppied" at the 6-O'Clock position, I'd consider that far more suspect Vs. a normal, concentric, swell toward the middle which poses no problem with either reloading or as a safety issue.

I have Dillon dies, Lee Dies, EGW U-Dies (made by Lee) and the Redding GRX die .40 push-through die. I make it a habit on all range pickup brass to run them through the U-dies before use. I have never found a case (out of over 30,000 so far) that failed to gauge or chamber. On loads fired in my guns, the Dillon dies have always done just fine as have, the Lees.

The Redding GRX gives me pause, though. I got one to experiment with more than anything else and although it seems to work as advertised (reduces the diameter near the case head), I'd have serious reservations using on brass that was significantly bulged in that area. Working the brass in the area it is hardest (and, was never intended to be ductile) just don't seem like a wise decision.

As an experiment, I took about 50 .40 caliber cases & lubed them, ran them through the U-Dies. As always, every one just cleanly dropped straight into my case gauge, rim first or mouth first. I then took the same resized cases and ran them through the GRX die. What I found was, it took a surprising amount of effort (same as un-sized brass) and, although the cases were already within SAAMI spec, the GRX still sized them down. It does do what it advertises but after using it, I don't think I'd feel comfortable recommending one for correcting serious bulges near the case head which, is it's intended purpose. On those cases, I think the safe thing is to toss 'em. Head separations have long been considered more prevalent in case-rolled brass and I would'nt be surprised if it isn't the case with the GRX once it's out there long enough to acquire a track record.

Which is why I suggested he take some fired brass, drop it in his chamber spin it and see if it's guppied or just bulged. I would load bulgied brass but not brass that did not pass the test above. If I got all that type of brass I would get a new barrel.

How would you feel about using it as a one time thing to get the brass sized for your chamber (assuming you didn't own a U Die). After the first time using a regular sizing die.

It would probably be fine in most cases Steve although, I personally would never feel comfortable shooting any of the truly "guppied" brass. I should mention that for whatever reason, I never seem to run across any like that though. I suppose the brass I come across is once-fired factory stuff and/or, has been fired through recent vintage barrels...just a normal, gentle, swelling of the overall case which is easily remedied with normal dies.

In using the GRX die, the cases seem to require more lube than normal resizing. Redding recommends Imperial Sizing Wax and includes a free sample with the die. Dillon's spray-on with the lanolin works OK but Hornady One-Shot seems a little too light. The effort required to run the cases through is surprisingly more than you might think. The die does not resize the cases for reloading...they must still be resized through normal sizing dies for adequate neck tension.

My reservation is this. If normal sizing dies fail to bring the case into specs sufficient to use, then the case is bulged very low in a part of the case that (1) should not be bulged anyway and (2) is the hardest, thickest area of the case that is not ducile and was never intended to be expanded/resized. This may be an unreasonable concern and doing it once may well have no ill effect. I would personally never consider doing it as a routine practice though, I feel it just can't possibly be a good thing. There are lots of instances where case-rolled brass has had case head separation failures and it seems to me that this tool is accomplishing a similar thing...resizing the case head area.

To answer your question directly, it may (or, may not) prove a useful tool and in the instance you named, is probably fine. Once it's out long enough to develop a track record we will know more. In the meantime, it's my opinion that the U-Dies are the more useful tool. In anything resembling a "normal" piece of fired brass it will not only size it to chamber in most all barrels, it will do it easily and with the extra margin of safety provided by more than adequate case tension on the bullet. I know everyone has their own opinions on this sort of thing and that's fine...I just choose to err on the side of caution rather than trying to salvage or extend the life of a few pieces of brass that perhaps would be better tossed.

I have an older G35 and I had the same issue with my brass. I opted to go the more expensive route and bought a KKM Precision aftermarket barrel. No no more bulging brass and it looks sweet, too.

And thats what I am talking about. Is his brass really bulged to the point of non-use. All brass bulges. My 10mm, 9mm even my buddies .38 Super Comp bulges a good amount. Is it bulging more on one side then the other? Thats the real question. Drop the bulged brass in the barrel, Spin the brass in the barrel. What happens?

Not if he has a older barrel that guppies his brass badly. Then I wouldn't want to load the brass no matter what dies you use. In fact no dieset is any safer then the other. That doesn't make any sense to me at least. They all resize the brass and if they pass the chamber check will shoot about the same.

If its guppied too bad to resize then it can never be reloaded. If its capable of being resized without wrinkling or gross distortion then why isn't it safe to reload? I assumed the OP possessed ordinary common sense and I didn't feel it was necessary to state the obvious.

If after resizing the brass springs back too much to hold a bullet, then it is work hardened and should be discarded. But this goes beyond the OP's original question.
