DIY STUCK CASE EXTRACTOR.
Yeah, I know, you will NEVER need this……………but you might. Most of us who have been in the reloading game for a while have stuck an insufficiently-lubed case in a sizing die and proceeded to pull the rim off it. RCBS sells a very fine little kit to get you out of trouble, but it costs US$20. Of course, if you misplace the factory kit when you need it, you might want to be able to put one together on Saturday night, and for half the cost, or less, you can make your own.
Obtain, as in, get, scrounge, find or even BUY a ¾” ‘close nipple’ and a ¾” pipe cap. I chose galvanized. Also obtain a ¼” x 3” standard hex-head machine bolt, a #7 HSS drill bit, and a standard ¼” x 20TPI tap.
Drill a 5/16” hole in the center of the pipe cap and assemble it tightly to the close nipple.
As with the RCBS kit, if you tear the rim off a case in your sizer die, remove the decapping assembly, drill out the primer pocket hole with the #7 drill, and tap it with your ¼” x 20TPI tap.
Set the base of your die into the open end of the close nipple, push the ¼” x 3” hex-head machine bolt through the 5/16” hole in the cap and thread it into the stuck case.
When the machine bolt bottoms (heads?) against the pipe cap, it will then extract your stuck case just as if it was a real RCBS thingy!
CAUTION! As most dies almost fit into a ¾” close nipple, you might want to give the die threads some masking tape or other protection if that stuck case is really stuck!
