I agree with 82boy. 1-1/2 to 2 ' of bedding @ the rear of a barrel is a good idea. It helps support the long, free-floated heavy-weight barrel. Wax-type shoe polish works great as a release agent. I also have used 'SnoSeal', a slick waterproofing agent for boots. it works as well, or maybe even better!
