Very interesting. Precision reloading data lists the following 16 gauge load using a Federal hull (by the way in the 60's Lyman listed the same reloading data for paper and plastic hulls:
Federal 16 gauge hull - 1 ounce shot, 18 grains Unique Federal 209A primer TC16 plastic wad, 9400 psi chamber pressure, 1180 fps muzzle velocity.
Use of the plastic wad would add a bit of chamber pressure over card and fiber wads as would the use of the 209A primer, but at 9400 psi I would feel comfortable shooting this load in my Damascus barreled Lefevers.
