Bullet maker D Dupleks builds some pretty wild expanding ammo. They’re unveiling new products for 20/70 and 410 calibers at the SHOT show. The company already makes the DUPO 7 Short Magnum for the 410-caliber Taurus Judge. “DUPO 7 steel slug expands at the first moment of impact when it hits material which consists water. Slug forepart opens till maximum, forms strong shape, which creates a powerful shockwave. When steel reaches breach point six regular splinters together with slugs main body creates 7 wound channels.” It should be interesting to see how they improve on that. Meanwhile, in the animation above, D Dupleks reckons homeowners can be judge, jury and executioner.
