Armor-piercing ammunition consists of a hardened steel, tungsten-carbide, or depleted-uranium penetrator enclosed within a softer material, such as copper or aluminum. Armor-piercing ammunition can range from rifle and pistol caliber rounds all the way up to tank rounds.
A tank is a tracked armored fighting vehicle, designed primarily to engage enemy forces by the use of direct fire. A tank is characterized by heavy weapons and armor, as well as by a high degree of mobility that allows it to cross rough terrain at relatively high speeds. While tanks are expensive to operate and logistically demanding, they are among the most formidable and versatile weapons of the modern battlefield, both for their ability to engage other ground targets and their shock value against infantry.
Rifle and pistol rounds are usually built around a penetrator of steel or tungsten. Aircraft and tank rounds sometimes use a core of depleted uranium. This penetrator is a pointed mass of high-density material that is designed to retain its shape and carry the maximum possible amount of energy as deep as possible into the target. Depleted-uranium penetrators have the advantage of being pyrophoric and self-sharpening on impact, resulting in incredible heat and energy focused on a minimal area of the target's armor.
Rifle armor-piercing ammunition generally carries its hardened penetrator within a copper or cupro-nickel jacket, similar to the jacket that would surround lead in a conventional projectile. Upon impact on a hard target, the copper case is destroyed, but the penetrator continues its motion and penetrates the substance. Similar armor-piercing ammunition for pistols has also been developed. It is of similar design to the rifle ammo above.
The entire projectile is not normally made of the same material as the penetrator because the physical characteristics that make a good penetrator (tough, hard metal) make the material equally harmful to the barrel of the gun firing the round.
Contrary to common belief, teflon or other coatings on the bullet do not in any way help it penetrate deeper. Teflon-coated bullets were meant to help reduce the wear on the barrel as a result of normal operation. Teflon coating was a trend that has largely faded, in part because of laws resulting from this isconception; there was a brief moral panic over these 'cop-killer bullets', which were said to have been designed to penetrate the body armor worn by police. A moral panic is a mass movement based on the false or exaggerated perception that some cultural behavior or group of people, frequently a minority group or a subculture, is dangerously deviant and poses a menace to society. It has also been more broadly defined as an episode, condition, person or group of persons that has in recent times been defined as a threat to societal values and inteNonetheless, I was really impressed with the realism when I was over at my cousins house - a cousin who has fireplace gas logs. The fireplace gas logs looked very close to the original. I had been burning fires in my fireplace for years. I grew up with a free standing fireplace in the middle of the room. Although my parents had installed internal heating, we still had the old wood burning stove that we could use to heat the house. It was great! Not only was it cozy, but it was practical as well. It really offered a cheap way to heat the entire house
Those fireplace gas logs looked so real. The style of the fireplace was remarkably like the one that I'd grown up with, and each fireplace gas log looked like it had been hand split and thrown on wood pile. I had to admit that, for someone who grown up burning real fire place logs it provided a tempting imitation. Sometimes I ask myself that if I grew up in a house that burns fireplace gas logs, would I never become attached to fire in the same way that people who grew up burning wood were? It really is hard to know!
I still like having a real wood burning fireplace a little bit better even though I like my cousin's direct vent fireplace. The fireplace gas logs are much better than I would have thought. But if you ask me, nothing beats the real thing. If you can't see the wood spark, can't stir the fire with a poker, and can't smell the smell of burning timber, it is not a real fireplace no matter how good it looks. Maybe it is better than nothing, but it is still not quite authentic. Tis is my opinion for now of course. Either way a fireplace is nice to have. Just be careful and enjoy it.
