Try changing the recipe on your patch lube to either 5:1, or 4:1, so that you have more Ballistol in the patch than presently, using the 6:1 formula. Burning patches often indicate your patch is not sufficiently lubed. The other source of burned patches is being too thin- like using a .010 Patch in that .54 cal gun. That is Not the case you are reporting, however.
If you don't want to change your mix of Ballistol and water, then by all means, try the wool felt wads to serve as a fire wall to protect the patches. OR, you can use a Vegetable Fiber Wad( 1/8" thick), or a cheaper "filler" like corn meal. The pre-lubed felt wads being sold are the most expensive of these three choices. Corn meal is the least.
You can also make your own felt wood wads if you buy a wad punch( Dixie GW, Harbor Freight) and pick up some old felt hats at the local Good Will, or Salvation Army thrift stores. The money you spend locally will go to good use. :thumbsup:
