Funny you should say that...I use Lee Case lube in the tube and mix it in a small eyeglass cleaner bottle with 91% Isopropyl. I'll toss the cases in a plastic bag, spritz them, shake them and spitz about 3 more times. This has been adequate to this point. I had just run low in the bottle and added more lube and alcohol. I suspect that I need to add more lube. You know it's good when the solvent flashes off and leaves a light film of lube on the case. I actually love reloading rifle cases. It's the hours of case prep that I dislike, especially when it turns into a stuck die problem.
I went to look for my tap and die set. Didn't find it, then looked for the EZ outs. Didn't find those either. I am somewhat disorganized and many times can find tools if I remember where I used them last. Having a three car garage and full basement doesn't help.
I used more penetrant...used a big Vise Grips until the rim was mangled past recognizability. Beat on the decapping pin until I was afraid my mallet would give out. Then I figured that if I was going to have to replace the die anyway I would try heat. Fired up the blow torch loaded with MAP gas and heated up the surrounding die...not cherry red or even close. A rap on the decapping pin and JOY...the pin and the case flew out the bottom.
I worked on filing off the peened end of the pin...I'll probably chuck that up in the battery drill and spin it in emery paper....if I can find the drill (just kidding...it's right where I used it last

)
Have to look at the die, clean it off and polish the bore...those suckers stay hot for awhile!
Thanks for the suggestions. I need to buy a universal decapping die and leave the pin out of the resizing die. Oh..and I need to get organized so I can find my damn tools.
