While editing my original post regarding the 8.6 Blackout brass now offered by Starline, I accidentally deleted the post. Sorry to David Reiss and another whose name I did not get prior to my error. I saw the email from the last poster and he correctly said I was showing my age!
Anyhow, Starline now has 8.6 Blackout for your black plastic toys. Perhaps they will offer 35 Remington in the near future.
With rifle in hand, I confidently go forth into the darkness.
