So went to shoot my subcompact XD40. Got new sights installed and testing them out. Well then this happened.


Big flash, and a minor powder burn on my hand. Gun tried to load another round, but failed due the brass still being in the chamber. Guys at the gun range got the brass out for me and then explained that in all his years of shooting he has never seen this before. He stated that it maybe have been a triple load or double load on the round. He was really condescending to me, in front of a lobby of customers, which kinda pissed me off.

Now this was my reload for 40SW. 180gr JHP, 6.7grs of Alliant Unique. Believe once fired brass. 1st reload, back in 2012, just now getting to shoot it, lol. I know you cant triple load a 40sw. And tried to double charge a case. Even if you could get a entire double charge you would not be able to seat the bullet. So my gun is at the smith right now. No visible damage, but probably some shrapnel in the internals. I figured it may have been a hot load with bad piece of brass. And my smith concurs. Now I guess im disassembling the rest of the batch and ditching the brass. Then start over with some new brass.

What occurred on the round before this event? Also, how much neck tension do you have on the rounds? If there is not a proper sizing of the brass to hold the bullet in place, and the bullet gets set back into the case upon chambering, it will create a high pressure round. Without knowing your procedures on loading, it's hard to say if it was a double charge (honestly, an unlikely event). The load is a max load, but it should still be fine under normal conditions.

!. Sounds like the load (6.7) may have been over max.
2. 180 gr has been the cause of most kB in 40 S&W
3. Check your OAL. It is easy to seat the bullet a tad too deep in the 40 case and this can quickly send the pressure waaay over the accepted SAAMI.

I think I would save the brass and toss the 180 gr JHP.

Someone will be along to say I'm wrong....

I could be way off track but, that brass doesn't look like to me the round was fully in the chamber when it went off. Cannot say I have ever seen a case head and rim stretched out that way before.

Agree. I had something similar happen on a 9mm once, not quite as drastic. The side where the rim is stretched so far was probably down over the feed ramp, unsupported.

Prior to this event, i fired four magazines through my gun without issue. I'm pretty sure the round was completely seated in the chamber. As the slide was completed closed. Also I dont believe an XD will fire unless the slide is completely closed due it be striker fired.


My loading procedure:
I use a single stage press. These rounds were loading with a lee die set. Have since switched to a lyman carbide die set. I make sure the brass is within proper length according to my data sheet. Chamfer if needed. prime. charge, seat the bullet. Check OAL. which according to my data sheet should be 1.12.

Again according to my data sheet...... Reloaders Guide Alliant powder recipes.(alliant's website)
40sw w/ 180gr speer GDHP 6.7grs of unique. Now it says for a 4" barrel and i have a 3.25"

Obivously i will be checking for updated data, backing down the load and starting again. No worries though. Thanks for the input guys. I tried to answer all the questions.

People who work at public gun ranges are typically complete a-holes.

Glad you are ok.

How do you throw your powder charges?

I started out using an RCBS manual thrower, never liked it. For charges of that size I got a larger variance in my charge weight. A little bit can go a long way!

I use a lee powder measure. Which is set lower than my desired load. The. Use a rcbs trickler to get my desired load. +- a 1/10th of a grain. All my loads are one at a time.

You trying to sell live ammo from the batch you personally had 2 blow up from? Sounds like a good time to learn a lesson stop buying cheap arse ammo from God knows where at the gun show and eat the loss. Trash can that stuff, someone is gonna get hurt.
