UPS delivered mine today! I ordered one last week to try out in my thumbhole Optima and after greasing it up and seating it with the tool and shooting it a few times, everything looked perfect. Again, zero crud ring with the American Pioneer 3f powder with Winchester W209 primers. Can't wait to see how much i have to adjust my scope when the BH209 arrives.
Very cleanly machined as well. No blow back but my head space is adjusted tight for W209 primers at the moment. I think the CCI 209 Mags will need just a tiny bit of adjustment.
