New .44 caliber Brooks mold.

[45-110]

Curious as to how the .060 poly wad and the cup base work in unison. Surely the blast must force the disc into the cavity then does it pop out in flight? All my old Tom Ballard molds where cup base and more than once I retrieved a few out of the berm that had pieces of the veggie wad jammed in the base after traveling 600 yds.
