Lotta apples and oranges being compared in this thread ....
Vegetable fiber wads, as has been pointed out, are not designed for the same purpose as wool felt wads.
Veggie wads are used as a "gas check" between the bullet's base and black powder, to minimize the effects of the hot gases on the bullet's base.
These wads are thin as paper and don't hold but a stain's worth of lubricant. They are useless as a lubricating wad for cap and ball sixguns, though a vegetable fiber wad can be placed between a greased felt wad and the powder, to discourage powder contamination if you carry your sixgun in hot weather.
Wool felt wads are typically 1/8 to 1/4 inch thick. They hold ample grease for lubricating the bore and to keep black powder fouling soft.
The paper-pulp wads used by reenactors contain no lubricant. They're designed to fragment within a few feet of the muzzle.
To make your own wads, you'll need wool felt wads. Many "felt" products today are not true wool felt, but made of polyester (plastic). Polyester felt will leave melted plastic in your bore.
Beware of window sealant felt. It used to be made of wool but for the past 10 years or so I've seen a lot of it made of polyester. Read the package carefully.
The best wool felt I've found comes from Durofelt, based in Little Rock, Arkansas. The nice lady who owns it offers sheet felt, made of pure wool, in various thicknesses. An internet search will find her site. Shipping is free to retail customers within the U.S.
I use Gatofeo No. 1 lubricant with my felt wads and have found it the best, in my 35-plus years of shooting cap and ball revolvers. The lubricant is named after me, because I used very specific ingredients, but the general recipe probably dates back to the 19th century.
My specific ingredients are:
1 part canning paraffin (sold in 1 lb. blocks in grocery stores)
1 part mutton tallow (sold by Dixie Gun Works)
1/2 part beeswax (the real stuff, beware of synthetic stuff. Most toilet seals sold today are synthetic)
All amounts are by weight, not volume.
This results in a medium-hard lubricant that is very good for all black powder applications. It is especially good with wads because the paraffin seems to stiffen the wad, helping to scrape out fouling.
Hope this helps.
