Possible copper in suppressor ?

[DLT]

I have been shooting my suppressor on a 22 creedmoor I had thrown together. I removed it to clean the barrel and noticed what looked like some kind of splatter in the last couple caps/ chambers of it. I have never had a baffle strike and never a bullet that came apart on out to 650yds as all rounds have gone on target. I’ll add it is a very accurate rifle so I wouldn’t think the bullets are starting to come apart
I’m running a 69 Sierra tmk 8 twist barrel at 3380. 43.5gr of N560. It’s not a hot load. Is this normal ? Pretty new to the suppressor world

Does the barrel copper up easily?

I don't see it as a possibility...
Any copper deposits not directly left by the bullet jacket in the rifling by contact are from the hot plasma vaporizing it in the leade area (at least, that's my understanding) and deposited a short distance forward in the barrel. I've never seen copper deposits in a muzzle brake, this would be no different.

Does the barrel copper up easily?

It does not, there was however more copper in it this cleaning than ever before. It was a 223 before I had it rechambered to a hotrod.
