I used and still use it for bullet lube, as it was designed - it does not foul the bore. I've never used it as a patch lube.
Try that same 'test' with any bullet lube and see what happens.
Does your dish washer produce the same flame temperature as black powder? What changes happen to beeswax and Vaseline or a mix of beeswax and any other softener including olive oil, when subject to the burning powder flame and pressure?
\All I know is what I typed out above. It did not foul my bore - in the .45 Longrifle, nor any of my BP ctg. guns - ever, however, it did it's job, of preventing leading and keeping the fouling soft from the previous shot and did not let fouling build up. As well the barrels, all of them, cleaned up as easily as they ever did - 1 patch for cleaning, 4 to 5 for drying and oiling.
As the late Paul Mathews noted, in "The Paper Jacket", after 5 or 10 shots, ALL the fouling should push out the bore with a single DRY patch. If it doesn't, your lube or quantity of lube is not good enough. His formula (60:40) works for me in both unmentionable guns and my in muzzleloaders when shooting bullets.
