The site mentioned brings up a notice that it no longer exists.
My concern with light, fast, frangible bullets is that they are wonderful theoretically and they will kill a block of ballistic gelatin, but deer do not drive around in cars, nor do they hide behind them and shoot back.
Some real life data, such as autopsy material and notes concerning the kind and type of cover and concealment the bullet had to pass through before it struck the target is a necesity, for proper terminal ballistic evaluation.
The "Magic Bullet" has been with us since the muzzle loader days, but a proper, efficient bullet for self-defense still eludes us.
However, I'm as enthusiastic as anybody about new bullets. I good test would be to obrain a quarter of beef, wrap it in an old T shirt, sweat shirt and leather jacket and shoot it through some light cover. That should separate the hopefulness from reality.
Of course, you would have to get the beef autopsied by a veterinarian, rather than at the County morgue.
X rays would prove the worth of the round beyond any shadow of doubt, even though the detractors would say that a body with blood flowing is different than a dead piece of beef.
FYI, I just unloaded my latest magic rounds from my pistols after a test that led me to return to swc bullets. However, I'm still hopeful.
Then....and this is of the greatest importance...after a shooting with frangible bullets your lawyer has his work cut out for him.
