It's said the filler keeps the small powder charge up against the primer ensuring ignition, rubbish if your primer can't fill the case with sparks it's stuffed.
In my opinion using dacron etc is likely to put a coat of melted plastic in your bore which I would rather avoid.
If you have access to old reloading books especially lyman ones there's no mention of fillers with any loads.

I bought some Trailboss off a dude in Katikati and he showed me how he used a smidgen of cotton off a cotton bud as his filler. Used it on both 223 and 308 rounds.Due to start some 308 as I have the Tok 151 308 pills.
