Unusual Norma bullets

[c1a1]

I was given a box of 100 .257 dia. 160 grain bullets today. Was told it was a small run for a new cartridge Called .257 Condor, circa 1960. Does anyone reload for this round?

A 160 gr bullet in a 257 must be a very long bullet. I believe to would require a very fast twist to stabilize.
