That's not a stuck case; THIS is a stuck case

I have made broken tap removers by cutting slots in a cheap 1/4 in drive socket and using it on the tap like a spanner wrench.I used a cut-off wheel in a Dremil tool to cut the socket. Good Luck with this, Lightman

2. I was indeed using One Shot. What can I use that won't foul primers and powder when I overdo it?

I use RCBS water soluble because it washes off in soap and water. I either put the brass out in the sun to dry or stick it in the toaster oven at its lowest setting. Heat below 400 F will not alter the structure of brass.

RCBS water soluble and Imperial sizing wax are my primary small base sizing lubes.

As for duding primers, don't sweat it.

I lube my cases to shoot in my Garands/M1a's. I don't have case head separations. I got the idea from a Distinguished HM gunsmith who never cleaned his M1a cases. He just rolled them in a towel saturated with RCBS case lube, sized them, primed them, all while greasy. He shot tens of thousands of lubricated rounds, when you handled his rounds they felt slightly greasy, not sopping or anything, and he said he never had a dud primer.

I did not have time to clean up the cases I used in this Garand match, I primed them wet, shot them wet, and they shot good out of a rack grade Garand.

Imperial Sizing Wax. Nothing else. One ultra stuck case was enough for me to learn.

I will try the slotted screw driver head trick if I break a tap. Last time I broke a tap was on cast iron cylinder head, just drilled it out and used an easy-out. Of course it was a large hole and tap. I am using carmex instead of one-shot now. washes off with hot water. 308 rims are weak, but the case head is pretty tough. You probably will need a slightly larger tap to remove the stuck case after you got the tap out.

Try sticking the die in the freezer for a while. Brass will contract more than steel when cooled.
