Has anyone tried Trailboss yet in the 8.6?
I've been experimenting with it. So far I'm up to 9 grains and getting excellent accuracy and quiet with a 250-grain bullet. This is out of a bolt action 12" Faxon Remage barrel.

Each charge is tricked from an auto-charger and it looks to be about the max charge for the bullet and the case.
