Hey, all you hull stuffers.
I have split a few hulls (3), to look at the internal profile of the same. Two were Remington. One Gun Club (green ribbed), and one black hull (ribbed) which were the same in their inner profile.
The third, was a Fiocchi ribbed target hull.
The basic difference was that the Remingtons (both) were tapered inside, and plastic bases were the same height.
When setting a WAA12 wad to where the powder would come up to in the hull, the wad fit the inside of the hull perfect. No gap between the inside of the case wall and the outside of the wad base seal.
Now, on the Fiocchi hull, the inside profile was straight, no taper. The WAA12 wad has approximately .040 to.050 of gap between the inside of the case wall and the outside of the wad base seal. I even tried a WAA12R, and the fit was the same, GAP.
With this being said, WAH-SUP? There is a great probability, that the powder is going to leak by the base wad seal in the Fiocchi hull.
Is there a tighter fitting wad for the Fiocchi hull that will not allow the powder to leak by the wad?
Aren't all of the wads the same diameter for a given guage? If so, how is it possible to stop the powder from migrating forward?
