Pistol Bullet Performance:
The last time we did a bullet performance test was during a course in PA early last year. At that time, friend and colleague, Mike Shovel from Cor- Bon brought out huge blocks of ballistic gelatin, and we shot them with a varie ty of commercially-available, high-performance pistol ammunition. We required
each bullet to first penetrate four layers of denim before entering the gelatin. At that time, we discovered that denim retarded and frustrated th e expansion of a number of conventional, hollow-point bullets. In bare gelat in, most expanded just fine, but the denim barrier presented a problem for all but a few.
Last weekend, again in PA, Mike joined us once more for an Advanced Defensive Pistol Course, The gelatin tests continued:
Many commented last time that they wondered what effect a heavy, leather jacket would have on pistol-bullet performance and penetration. So, this t ime we required each bullet to penetrate a leather jacket AND four layers of de nim before entering the gelatin. Each student subjected his own, carry ammunition to the test. Here is what we found:
The combination of leather and denim frustrated most conventional, hollow-points. Most traversed the gelatin with badly-compromised expansion . Some did not expand at all. Even Cor-Bon's vaunted PowerBall (45ACP, out of my Detonics) did not do well in this test. I was surprised, as few rounds wil l out-expand PowerBall, but the layers of clothing, combined with the Detonic s' short barrel, conspired to thwart performance.
The one round that expanded consistently and completely, despite the leathe r and denim barrier, in all calibers, was Cor-Bon's DPX! DPX, in 40S &W, 45ACP, 357SIG, 38Super, and 45AutoRim, were all unimpressed by the leather and denim. Even 380Auto DPX, out of my little Kel-Tec, was immune. It expande d symmetrically and completely, penetrating nine inches of gelatin, after penetrating the clothing.
I am more persuaded than ever that DPX provides superior performance in the widest spectrum of circumstances, consistently outperforming any other bullet of which I am aware.

besten Defensivmunition (bei Faustfeuerwaffen, bei Gewehren passts).

In den Expertisen der IWBA und allen mir bekannten standardisierten (!) Tests bildet die Barnes DPX Vollkupferhohlspitzmunition
(in Ö. wäre die deshalb auch ohne Schützenpass völlig legal!) den Höhepunkt momentanen Defensiv-Geschoßdesigns und lässt
selbst die Federal HST, Winchester Ranger SXT und CCI Gold Dot (die momentan den Standard bilden) hinter sich zurück.

John Farnam (http://www.defense-training.com/quips/10Apr06.html) recently commented on Cor-Bon's DPX range of defensive ammo. Since this stuff is available for both hand- and long guns, I'm posting it here in GGD instead of a weapons-specific forum.

We had a chance to look at the Fiocchi 92 gr Expansion Mono Block this week; as can be seen, it was less than impressive...

Fiocchi 92 gr Expansion Mono-Block (9EMB) fired from G17 at ave vel of 1315 f/s; 5 shot ave below:
BG: Pen = 12.6", Ave RD = 0.56", Ave RL = 0.54", Ave RW = 93.5 gr
4LD: Pen = 16.1+", Ave RD = 0.36", Ave RL = 0.55", Ave RW = 93.5 gr

Even if the EMB works perfectly, it is still problematic. The expanded portion of the EMB is far behind the leading edge of the projectile. The temporary cavity forms at the leading edge of the projectile--in the case of the EMB, at the front of the upright post, much like first generation Hydrashoks with the large thick center posts. Think of the EMB like a Hydrashok on Viagra. The TC forming at the front of the erect post can result in the tissue being stretched away from the expanded jacket at the back of the bullet, thus preventing the expanded bullet edges from touching and cutting tissue. With deforming handgun projectiles, the expanded bullet edges need to be as close to the leading edge of ther projectile as possible for maximum tissue disruption to occur. Unfortunately the EMB fails in every way...

Oder lieg ich da falsch??

Federal Hydra Shok ist Teilmantel-Hohlspitz, gaaaanz bööööse -> verboten
Magtech Guardian Gold oder First Defence sind aber Vollmantel-Hohlspitz und daher erlaubt
