Jim, post some photos id love to see them.

The source for the 170 grain fmj for 30-30 in executions to the best of my memories was a scanned gif of a document with what looked like federal department of corrections seal information.

There are companies like Woodleigh and one in Australiaicon/new Zealand that make steel jacketed with copper overlay in round nose configuration but they don't have loading data. And cutting edge makes bullets that are almost round nose from solid copper, but don't give any safe to use loading data.
