Owlelope,
Go to the reloading section of your local gun store and get a box of bullets to fit the caliber of casings that you have. They usually run from about $16 to $25 for a box of 100. I use .308 cases with 168gr. boat tail hollow point bullets because that's what I have.
Easy to work with and not a major investment. Look much better than using a kit nib.
Soldering is an easily acquired skill. Just try what the tutorials say and you'll be doing great in no time.:biggrin:
Anything is possible if you tinker with it long enough and aren't afraid to try something to see 'what happens if I....?' A friend suggested that I make pocket bullet pens using .308 cases as that is the same as the 7.62mm the military uses and we have a bunch of those folks next door. I read the tutorial in the library but didn't have any of the kits that he suggested using. I figured out a way to make the same thing using Slimline components. Different route to get to the same destination.
Give it a try. No one has to know about any learning experiences along the way.
