9 mm brass too much "bell"

[jharry]

I picked up some 9 mm brass recently (thrown into a deal) that has had the opening incresed to about the same size as a 40 sw...... unfortuately they all have new primers in them also. I havent even figured out how this could have been done, unless he used a 40sw expander die (maybe ???) to open the hole for the bullet to set in the cartridge.

It did not seem to split any of the cases though.

There looks to be about 500 of them - I cannot think of a good way to save them and make them safe and useable again

Thoughts/Suggestions?

At least deprime them and get something out of it.

Depending on which type of press you have, just remove the deprimer from your resizing die, and resize them again.

Leave the primers in the cases.

Do a few to see if it works. If it does, then just go ahead and reload them mild.

Easy peesey lemon squeezy.

If I tried to deprime them - I would run the risk of the primer kaboom, I would expect.

I could try the re-size - not sure the flared end will even go into the sizing die.

I could see them not fitting into the sizing die if the flare is really excessive. You should be able to run them through your seating die to remove the flare.

I've deprimed hundreds of live primers, none have ever gone off. You may have to use a universal de-capping die if the bell is too large to go into resizing die though. The bell probably was made with a 9mm die, you can really make large bells if you set it too deep.

Now that they've been stretched so much even if you can get them back to size they probably won't last more than a couple more loads. And since who ever you got them from obviously didn't know what they were doing I'm not sure I'd trust the correct primers are in them.

So, personally I'd through them out.

yea good idea i was going to say the same thing the seating die is often good and wide mouthed

if they still dont fit i would try to round up the pusher bar from a lee bullet sizing kit that is small enough to fit inside a 9mm (like the .311 sizing kit) and push them butt first through a expanding die missing the innards

I'm sure they are the correct primers because I bought all of his primers too - all he has ever used were Winchester small pistol

I have never tried to decap a live primer - I am surprised it is something to consider - there must be a technique to this to include not moving the decapping pin too fast into the primer?

Here's how I do it. Place it in the press like any other brass.

You gotta really be moving to set one off. I did them at my standard pace with no problems. Empty the primer catch every 5-10 rounds.

Worst case, one goes off, sets off the other 10. No press damage, because the primer will back out of the brass, not shoot your decapping pin out or anything.

Try running them through your crimp die, with the die set way out so it's not crimping. I wouldn't be too concerned about them having the right primers, except if the guy would do this to his brass then who knows what other dumb stuff he's been doing?

I've deprimed a couple hundred cases too. I haven't had one go off yet (knock knock). The procedure would vary depending on the press, but I just catch them one by one so there's no chance of multiple detonation. If you think about it, the spent primers come out in one piece with no visible damage to the underside so the new primers will come out too. Just move the press arm slowly and I'm sure you won't have a problem.

Are you guys saying he can salvage the primers and to toss the brass?

[sequoia_nomad]

I'd say his best bet probably be to just toss 'em. 9mm is amongst the easier to find cases, and the brass will last through many reloads as long as it doesn't get overworked by too much belling or some other ignorant loading procedure.

[jharry]

I may try to save the primers - It may be the best solution.

I would love to be able to save the whole piece- even if I loaded 1 more time and then tossed the brass away - wouldn't be much different than most guys who don't reload at all.

If it was me, I would try to save the brass too. However, since I can't see it myself, I don't want to recommend something that might be dangerous. Considering that 9mm is a fairly high pressure round as it is, depending on how stretched out the cases are, it might be better to save the primers and toss the brass. I always load things on the mid to low end of the scale, so I would probably keep them if it wasn't too hard to get them back into shape.
