.380 compared to .9mm

XDRoX was kind enough to give me 50 9mm to go shooting today. Its the ones where he did 300 in 30min or something like that. Well as i am shooting and have a miss fire. Thinking his speed turned into a lack of quality, so i return his one bullet (so he only gave me 49). We pull it to see if Mr. Perfect missed a powder charge. Nope there was powder. But after further inspection he yells at me "this is not my bullet its a .380 auto." well that's what you gave me. So we where both confused on how this happened are .380 and 9mm pretty much the same. I think it did not fire because it was not fully against the bolt face so the firing pin did not pierce it enough (then again i do not know what i am talking about). So everyone Chris can add .380 auto to his signature.

Another name for .380 is 9mm Kurz, which literally translates to 9mm 'short'. Very easy to get the two cases confused.

(Especially a couple of rookies. Don't worry, you'll learn, it takes a while.)

Why did it not fire? Using a Ruger P95

If the extractor didn't hold it against the breech face it was too short to headspace in the barrel. Don't know anything about a Ruger P95 so I can't help you there.

Correct. The 9mm & 380 share the same bullet dia, but not much else, shorter, tapered case, smaller case head. I hate having to sort them out of my range pickups.

380 is a shortened 9, 40 is a shortened 10, 38 is a shortened 357 and so on. Case is shorter, diameter is the same. The load data is definately different though. I found a couple boxes of speer 95 grain 9mm tips in my cabinet. I don't own a 9. I did years ago but not anymore. I loaded them all in my 380 casings and they shot great.

I have fired a 9mm out of my 10mm. It must have been held under extractor so it could be fired. I still have it. Balloned up to .40 size on the end.

.380 case is much different in diameter then the 9mm.

I was referring to the bullet diameter. The longer cases of course have some heavier bullets also.

Before I started pre-sorting my tumbled brass (to eliminate undesired headstamps as well as to separate out .380), I'd accidentally put a piece of .380 brass in my 550B while loading 9mm.

It would resize, but it would never prime? Either it's a different shellplate, or different pins are used... but the case would always move out of the way. Not sure how he was able to do that, he's using a 550B also, isn't he?

550 Uses a different shellplate for the .380 then the 9mm. But if things lined up perfect it could prime. Biggest thing is the .380 case is so much smaller in diameter then the 9mm that it doesn't size at all. When I hit a 380 case while loading 9mm the handle slams downs so fast it's impossible to not notice that the case was not getting sized.

I am on a 550b. Like Steve said, it probably just lined up perfect because I definitely loaded it on my 550b. There probably was a change in pull, but I didn't notice. I was loading a mix of brass from once fired to 20+ times fired. A few were even already sized. Some of them are really hard to size while others are like butter, which is probably why I didn't notice. I don't case lube BTW.

I will do a better job sorting from now on. Every now and then I pick up a 32 auto and almost put it in the press, but I can feel the size difference with my fingers. I really just need to sit down and go through my 9mm brass, but it's in the thousands. I bet there are a few 9mmMAK in there also.

After I tumbled my next "batch" of brass, I sit down in front of the TV with several bins and a small flashlight. I grab a piece of brass and shine the light inside to make sure there's no "crud" in there. If something were, it would reduce the volume, potentially causing problems. I then flip it over and check the case itself briefly, then the headstamp. There are many which I don't care to reload. Those get tossed. I also check that it says 9MM and not .380. I can usually detect it just by the size, but sometimes not.

I don't currently reload .380, but I keep the brass. I may decide to do it someday, or I can sell it or something.

My time at the press has been WAY more productive, as I don't end up with a piece of WCC (military brass with crimped primer) as it was culled during the sorting process (I do keep it though). I also haven't accidentally put a piece of .380 in... it's been a LONG time since I did that.

I can do a BUNCH of brass in several hours in one evening... it's just part of the QA process that I like to follow. Works for me. YMMV.

I've managed it a few times on the SDB, getting a .380 primed, while loading 9mm.

The XL650 will do it no problem through the casefeeding system. I've had 3-4 got through so far... good thing is the RCBS lock out die caught it each time.

When I'm unlucky enough to find a .380 case that got picked up with my 9mm, it always has an unusual feel when I decap/resize. So I've never reloaded one.

What do you guys think would have happened had the round fired?
Anything bad?

I was throwing 4.5gr of WST, which is a very light load, so I doubt the smaller case would have created unsafe pressure. I also use 124gr plated bullets, so although I doubt most people shoot 124gr in 380, do you think it would have fired safely?

Another question is did the case have the full 4.5gr of WST in it, or would the shorter case not have fully operated the powder throw

I should have saved the powder after I pulled it, but I dumped it out. I could try to run it through the 550b again and see what happens.

All the dillon machine use the same powder funnel for .380 and 9mm an "F" so yeah you would have had powder in the case. Provided you set the OAL short enough it would most likely crimp. As stated before if it was centered on the breach of the gun with the rim under the extractor.... then yes I think it would have fired and the case expanded.
