45 Super is externally/dimensionally identical to 45 ACP or 45 ACP +P and is designed to be used in 45 ACP Semi-Auto pistols that have been modified with a stronger than normal recoil spring and a shock buffer, plus a few other modifications. While you can shoot 45 Super out of some stock 45 ACP +P pistols such as the Glock 21, HK USP, or the full-sized all steel 1911, it can cause excess wear and tear on the firearm if you do not have them modified to handle the extra pressure and slide velocity of the 45 Super.
Hi-Tek coating allows you to enjoy the benefits of a hard-cast projectile and the cleanliness normally seen in copper jacketed/plated rounds.
Hi-Tek is a polymer based compound* that not only reduces fouling in your barrel, but also substantially reduces airborne lead contamination (allowing for use in some indoor ranges). The elimination of the wax lubrication combined with the reduced airborne lead contamination results in considerably less smoke produced with each shot.
*Hi-Tek is NOT nylon, PTFE (teflon), or Molybdenum
Hard cast flat nose bullets are non-expanding, powerfully penetrative bullets that are designed with your woods defense needs in mind; whether fending off wild hogs or black bears, the hard cast flat nose bullets are consistently effective in taking down any wild animals that you may encounter.
In contrast to the round nose non-expanding bullets, the flat nose bullets are able to pierce through dense bodies of mass while maintaining their nose forward position, which is optimal for maximum penetration.
Nickel-plated brass casings, our nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel-plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.
