No experience with Schuetzen loads, but I will warn that Dacron over low pressure loads melts, rather than burns, and the result is an unholy mess.  I switched over to kapok before abandoning fillers altogether.   Still have plenty if you want to try it.

Someone will recommend using a thin disk of floral foam, which makes sense to me, although I have never tried it.

The chronograph will tell the tale, and is the best way of determining whether you have uniform ignition, shot-to-shot.  That, after all, is really what you are after.

I always found cards cut from beer cartons to make the handiest wads. Crease them a little, and insert so t hey straighten out under pressure from an appropriate "pusher", which should have a stop at an adjustable place.

My JP Sauer in 8.15 does fine with a stop ring bullet and no filler or wad. Easy to load using fixed ammo. It’s a stalking rifle so I only fire it offhand. No idea of accuracy off the bench at 200.  At under five pounds and barrel sights, that’s not its game.

I'd like to chase the best accuracy I can get. I'll probably do stop rings for offhand, but I can't help being curious about just how well she (and I) can do from the bench. Chris, I have fire formed brass from my .33-47 High Wall. I'm thinking maybe chamfer from the outside on one and from the inside on another to sharpen them and make wad cutters to get two slightly different diameters to try to match the interior diameter of my 8.15 brass -cutting cardboard wads like you suggest to experiment with that .10-.20" distance off the powder. I'm still nervous about them staying in place, though. Did you ever experiment with fillers instead of the wads?

Never use Dacron it is the one thing you can do that will increase your chances of ringing a barrel faster than any other. If you feel you need to use a filler use Kapok or a cotton ball teased out.
