I'm all ears, but the the reasons I have heard not to use dacron was possibly ringing a chamber. From the information I had found, this was caused because people would pack the dacron down on the powder, so when it went off, the compressed was of dacron woul accelerate, then hit the base of the bullet and cause a pressure spike. I think you could do the same thing with TP too. When I load, I make sure to not tap the wad down, I use the bullet to push it so the dacron is pressed on the base of the bullet with no air gap.

I should also note that this is in a Browning BPCR with a badger barrel, so not an antique, so less risk of soft metal

Just got back from the range. Groups weren't great, but that is likely because it was pretty breezy and no wind flags, I also didn't have a great bench setup, but... I fired 26 rounds over a Garmin chronograph and here are the results:
Min 1097.5
Avg 1109.7
Max 1119.7
ES 22.2
SD 4.6

I don't have the federal or Remington pistol primers, but I do have CCI, I'll try some on my next trip. Biggest issue is the range I have gone to for the last couple weeks has no way to read wind, and I sure as heck am not going to put my flags out on a public range. Will be interesting when I get back to my private, schutzen range

Ah ha!  So you are admitting that you shot the leg of my wind flag stand at Tommy’s with your muzzle loader!   

The only one putting holes in my flag stands at my home range is me.
