    powder coating

    I have been tumble lubing my bullets using the 45 45 10 mix and it works well for 38 and 45 at 800fps, but I can't help myself and want to try powder coating. The Eastwood Ford blue looks great but Eastwood's instructions say bake for 400 degrees F for 20 minutes; will that cause hardening...
