5.56 and 7.62 Case Capacities

Cases are difficult to find these days, and when you do find them they tend to be expensive. For the most part people who are looking for cases can only find them from military surplus sources. However, there is a consequence of using military cases: they tend to be thicker and heavier than commercial cases. This comes from the extra weight in the head and web. The resulting consequences are that they possess a reduction in volume, and powder charge. 
There are websites that sell used military surplus cases, such as Everglades Ammo (evergladesammo.com). Our Load Data Editors have ordered these cases, and tested them out to find exactly what the reductions in volume and powder charge are, and write an article about their findings. It cost $85 for 500 cases, delivered, and only three of them were unusable. We also found that the 7.62 cases work well as a substitute for the .308 Winchester cases, and at a very reasonable price.
Our experiment also included the .223 Remington, and discusses the weight and water capacity in grains, and velocity of these cases.
