I have been watching all of the posts about using shell cases for pens and I think I came across something that might be of some help to others.
The above pen is not perfect - but it shows a concept that is pretty darned good.
USE A SLIMLINE and a .308!!!!
The 308 shell length is within 1/8" or so of being the same length as the slimline tube. The 7mm tube will fit inside the shell very nicely.
What I did was drill out the primer pocket with a 7mm bit. Then I put the 7mm tube in and left just a small piece out of both ends and then turned the top and used micrometers for the size. It spun free on the mandrel.
Then I glued the tube into the case with CA. The bottom was easy. I made sure that I kept the top of the tube in the top of the case centered in the shell while the bottom set. Then I ran a very small bead around the lip of the top between the tuber and the case.
Then I trimmed the case. Be sure and trim the top too. As any reloader will tell you the lip of the rim will go out of round after firing and they are often reamed back into flat and round.
Now, put the case back on your lathe and polish it with MM from 1500-12000. Then spray a few light coats of Deft on it. Unfortunately I trimmed this one after I sprayed it so mine doesn't look as good as it did.
When you press the pen tip into the top of the tube the tube swells just a bit and you get a perfect fit. The fit is so good that it looks just like a live round - even to the hollow tip appearance.
Now I just need to find a better rifle clip.
Again, it's not perfect but it sure was easy.
