or so I was told by the old fella who showed me how to make subs.

he just used the fluff out of a pillow by the looks of things

I decided that looked like it wasnt the best way forward and went with trailboss

his subs were A LOT cleaner than trailboss if that matters to you, but they were no more or less accurate

I understand that pillow fluff is polyester and the same as what some reloaders refer to as "Dacron". It's main application is that the powder will have the same position up against the primer whether you shoot horizontal, up or down. Some powders like TB are "position insensitive" but I don't think that means it makes absolutely no difference to have it stacked consistently against the flash hole. I salvaged some from a torn pillow and into a larger jar than I'll ever finish as you need only a tiny amount to do the job, you don't stuff in as much as you can.
