Can anyone give me a short list of what cal. shell casings can be used to make a bullet pen when using a slimline pen kit ? What cal. casings will work without having to modify the casing ?
Thank you
I have made several from 7mm mag shells. Drill a 5/16 hole in the primer end and then hammer a 2018 (5/16 brass tube might work) into it and the neck will stretch just enough for slimline hardware to fit.
