so ive made a few tips from some .38 casings and some old broadheads, but im looking for some new ideas. anyone with some ideas or pictures this would be highly appreciated.

Go to the How to Section on the main page there should be a few topics on them.

I made some out of wing nuts and Allen head screws from hardware store. There was link somewhere on how to and what size. Mine turned out to be 125 grains, which is perfect for me.  I'll try to find the sizes when I get home.
