New black powder

Looks like it is clean for 80 gr. on that patch.. I love shooting black powder.

Looks like a good bit of blow by on that patch

no blow by at all. Fouling on a greased patch. Blow by leaves cuts/holes.

Blow by doesn't always cut the material. These don't look like gas leakage to you? Regardless, I guess if the accuracy is where you expect it then it doesn't matter

Not at all, no swabbing between shots, so the next patch is just picking up fouling.

That's a tight cva barrel with a .020" patch
