I once made a batch of wads from Duro-Felt and lubed with a mixture of beeswax and mutton tallow. After I got done shooting the fouling was so soft it took one patch and the bore sparkled!! Best wads I ever used, I need to make me some more for my Remington’s belt pistol.
Store bought wads are NOT as good, and they are EXPENSIVE. Some places want $10 per bag of 100, and for what you’re getting, it’s an absolute ripoff. Making wads will save you a lot in the long run, you can make your own bag of vastly superior wads for $2 or $3 per hundred. Cast your own balls, too! With powder and caps rising in cost each year, it can be worth it if you shoot these guns a lot.
You can go REALLY crazy and make your own powder AND caps too, but both ventures are labor intensive and potentially unsafe if you don’t know what you’re doing, and I think at that point it’s at the level of diminishing returns.
