RE: Making your on wonder wads.
The other thing you need to think of whether you want to make them or purchase them is.. some like to tinker. I have bought them and still have RMC wonder wads in stock for my rifles. I like to punch my own out I guess for the same reason I like to cut my own roundball patch from a strip instead of a pre lubed patch.. it just gives me a little more pleasure knowing with my traditional rifles, I shoot black powder, I cast my one ball, make my own wads and patch, make my own lube, and have a lot of fun doing it.
I can sure understand why someone would choose to buy them also...
