I think you're right. The plunger tubes that don't fly apart look almost like there is a slight roll crimp on the end.
I've considered taking a Stanley 3/16 nail punch to it but I figured unless I come up with a very strong way to support the opposite end in the vice, it will just pop off and then I'll be screwed. The legs are not very strong.
The 3/16 punch has a recess in the end. It looks like it could roll the end of the tube inwards slightly and evenly.
Thanks for letting me hijack your thread with an unrelated question.
Take that sucker out back and test fire it.
it is on the subject--plunger tubes and oh what FUN!--LOL!
