Messed up sizing on 500 rounds

[evan the cdn]

I loaded 500 rounds of 9mm on my Dillon 650 without bothering to check the height of the sizing die so they weren't sized narrow enough all the way down.



Are there any options other than pulling all of them? Could I take the deprimer out of the sizer and run them all through with just that die on the toolhead?

Are you sure they won't chamber anyways?? I've found that my pistol is not that fussy about the resizing die being perfectly set.

Yes. The only way I could get the brass out of my M&P and SP-01 was with a brass rod. The bolt cycled when fired on my RRA 9mm AR but I still don't want to use them in it because I wasn't able to pull a loaded round out of the chamber to clear it and that is sometimes necessary.

Would a Lee Factory Crimp die size the loaded case for you? I think it might.

Given the situation, /\ this might be the only recourse. Or maybe run them through a Lee Bulge Buster die.

I don't reload pistol, but for rifle you can get a body die.

 

[fogducker]

take out the decapping pin/rod and just re size

What's your OAL?

You can't run 9mm through a Lee Bulge Buster as you can .40S&W or .45ACP because 9mm has a tapered case.

Are you using brass shot through your own guns or was some of it range pickup which may be Glocked?

Did you remove the barrel from any of your guns to do a plunk test?

x3 and do yourself a favour and buy a $20 guage. Check every 10 - 20 rounds.

Lesson learned Everyone does it once. I spent a couple of hours once as a reloading noob, lovingly crafting a box of 50 .303 rounds to shoot out of my "new" enfield rifle. Trickled the puwder, chamfered and deburred necks and primer pockets and flash holes, checked the overall length and they were all perfectly consistent. Then, i tried to load them into the mag, and they were too long for the magazine. I had to single load them all. Needless to say, my FIRST step now with a new bullet is to check that a dummy round will actually fit in the gun

Thanks guys. I'll pull the deprimer out and try that next week.

Right. Good catch, thank you bro.

From what I have seen reloading different brands of 9mm brass, Federal has thinner walls than Winchester or CCI or most of the others. I say this because when reloading with Berry's .356 plated bullets, almost all the finished reloads will show a little bulge due to the bullet pushing out the case walls....all except Federal brass.

So IMO, running any loaded rounds through a resizing/depriming die (minus the decapping pin) will definitely resize the brass. As well, the resizing die will also resize the bullet in most brass brands. Federal will be the least affected, hopefully this is the brand you got.

If you can see bulging in your loaded rounds, post-sizing will swage your loaded bullets into a smaller diameter.

Anyways, at least you will be able to shoot these questionable rounds though accuracy or keyholing might be issues due to undersize bullets.

Check for what?

Update: I haven't fixed the bad rounds yet but I've made a discovery.

I went to the range today with some rounds that I loaded after properly adjusting the resizing die as per the manual. They functioned in the AR and the M&P but still wouldn't fit into the chamber of my Shadow. When I got home I cleaned the crap out of the chamber and they still wouldn't fit. For interest's sake, I tried resizing a case without seating a bullet into it and it fit just like it's supposed to.

Resized case without bullet dropped in as it should:

Loaded round with the same height on the resize die.

Apparently the resizing die isn't my only issue.

Bullet not seated straight, or heavy crimp buckling case. My guess.
