Has anyone ever used copper powder as an additive in the corn cob media to shine up brass which is stained?
If so, were there any adverse reactions on the brass?
40 S&W OAL for 180gr round nose.
Does anyone have an OAL for this?
For some reason, I ordered 180 grain round nose (RN) from Berry's.
I know it can be done, I just don't have any sources of information for what the OAL should be.
