I see some very interesting shotgun cartridges with slugs, big shot, balls, and other projectiles but I don't see much in the way of Paradox cartridges. So I will add a few.

From top to bottom:

Antique H&H 10ga Paradox cartridge (steel capped, see page 33 of 1910 catalog)
Antique H&H 12ga Paradox cartridge (hollow point)
Current H&H 12ga Paradox cartridge (740gr solid)
Bullet from current H&H 12ga Paradox cartridge recovered from clay bank (it took a lot of digging)
