Copper wash?

[Harter66]

I've seen 303Guy talk of toughing up an alloy by "forcing" copper into it via tinning copper parts and putting them into the pot.

Now I'm not sure how that all works exactly, something involving boundry exchange maybe. It seems to me that w/the volumes of range scrap that I use I must have nearly copper saturation. My communal range sees quite a bit of TMJ,plated and copper washed ammo. All of which is I think electro- plated. As I understand the process cold bonding of copper to lead,sort of tinning lead w/copper. I sort most of the rimfire 22s as very/dead soft for RB,ML and slugging.

Does the bond layer and or wash alloy in or dross out?

Maybe the question should have been limited to "where's the copper wash and other half of the electro plate copper go, alloy in or dross/slag out?"

Sounds like paying Rotometals for a lead analysis is in order. That should tell you what you want to know. I saw they posted on here you could do 5 different samples for one $65 test fee, IIRC.
