This is definitely not the kind of ammo you'd shoot every day for practice. It's high pressure premium hunting or self defense ammo, best used sparingly for when you really need it. DT uses all nickel plated brass cases, btw.

Gold dot bonded core jacketed hollow points are designed by the same designer that made the old PMC Starfire (almost the same technology) and the same guy that designed the Remington Golden Saber. It is the extremely tough nature of that bullet that allows such high velocities combined with such deep penetration.

For instance, the DT 9mm+P 115gr loading has about 50fps more velocity than Cor Bon 115 (Loaded with a conventional Sierra JHP), but it achieves between 2"- 3" more penetration as well.

The DT load matches Cor Bon 110gr Powrball (1500fps) in penetration, and exceeds it in expansion (9mm Powrball is 12" penetration and .64 expansion and has no bonded core jacket)

I've had a ballistics gelatin tester for the Pennsylvania State police flat out personally endorse the Gold Dot design. He says it always expands, regardless of the intermediate medium.

I'll get some recoil impulse data that i saw browsing the web last night and post it here.
