Intermediate Cartridge Data Although the images are rather crude, they hopefully illustrate some illuminating features about each of the cartridges. Accuracy of 5.56mm [ 1 ][ 2 ], Accuracy of 5.56mm Mk. 262 [ 1 ], Accuracy of 6.8mm Remington [ 1 ], Accuracy of 6.5mm Grendel [ 1 ][ 2 ], Accuracy of 7.62mm x 39mm [ 1 ][ 2 ], accuracy of .300 Black-out, Accuracy of 5.45mm [ 1 ], Accuracy of 7.62mm x 51mm NATO [ 2 ]  *Tests with the 6.5mm Grendel showed sub 1-MOA with nearly every cartridge, and an average of about .5. The lowest was .3 MOA, out of a 1500 dollar AR-15.  **The limits listed are at about the average or maximum for poor accuracy. Conservative to estimates, some are more or less close to what their figures would be in real life, out of ordinary firearms. While the Ak-47 can easily achieve 3 MOA for instance, many weapons are nearly 50 years old with plenty of wear and tear, which puts their accuracy closer to 4-6 MOA. These are largely for new weap...

Aluminum Oxynitride - Transparent Armor Aluminum Oxynitride , dubbed by some to be "transparent aluminum", is essentially a high strength ceramic polycarbonate composite, using laminated layers of a high strength alumina, sapphire-like ceramics and traditionally bullet proof plastics. AlON is optically transparent (≥80%) in the near-ultraviolet, visible and midwave-infrared regions of the electromagnetic spectrum. It is 4 times harder than fused silica glass, 85% as hard as sapphire, and nearly 15% harder than magnesium aluminate spinel. The high hardness, coupled with the high strength, particularly contributes to it's ballistic resistance, of which just 1.6 inches can stop a .50 caliber BMG, compared to 3.7 inches for traditional glass laminate bullet proof glass. The material is one of the strongest transparent armors in existence, and would be useful for soldier's visors, armored vehicles, and even aircraft. Of particular interest would be used by infantry, who...

Idea for body Armor - M5 Fiber and liquid Body Armor Although I have a lot of ideas for body armor and there are a lot of new emerging materials that could certainly replace those currently in existence, a thought I'd have for quite some time is mixing M5 fiber, an aramid fiber similar to kevlar, with the liquid body armor concept, a non-newtonian fluid designed to enhance the performance of the material against projectiles and bladed weaponry (such as knives). The basic problem with the liquid body armor program has largely been temperature, that is kevlar degrades rapidly at higher temperatures and doesn't last very long in the field after being heated to high temperatures, and becomes weaker. While there are currently measures being taken to reduce the heat of the liquid-body armor oven-treatment, an alternative would be to use a material that is more heat resistant, such as M5 fiber, and more chemically stable, that could not only withstand the heat of the oven, but also b...
