Can you show us something.??? Thanks.Mark,
Do you mean the look-alike pen kit, or a pen made from a real rifle cartridge? I've made "bullet" pencils from a 30-cal cartridge using both the Pentel pencil mechanism, and with the Schmidt pencil mechanism and a cigar kit. A pencil based on a perfect-fit or slimline-pro kit should also be doable.
Regards,
Eric
Here's a laser-marked .300 Weatherby pen/pencil set I made from Sylvanite's components and Axis Deer anter:
The pencil uses a nice Schmidt mechanism.
