[quote=@iHxzardx] [@MatthiasAngel] Marines now-a-days are only using .223's as regular ammunition and with this being future a bullet advance could have been made and possibly the .22 is strong enough now! My character is probably going to use a .22 .223 or simply an air rifle most likely, along with a spear or sword of some type *shrug* all im saying is that a .22 or .223 is an excellent marksman rifle. [/quote] Wh...the .22 is not going to be "strong enough." You can't just make a bullet stronger. The .22 is small, the lead is round, and the cartridge holds very little gunpowder. It's also a rimfire cartridge, which means it can misfire. You can't wedge a .223 in with an air gun or .22. The .223 has a longer, sharper bullet, it's center fire (much more reliable) and it holds at least two or three times as much gunpowder. Air rifles hit targets and bounce off at a few hundred FPS. A .22 bullet is about the size of an air rifle BB, but it is heavier and clocks in at 1,400 to 1,800 fps. It'll go through skin and muscle but at medium to long range it won't do serious damage to organs and leaves very little blood. A .222 is heavier, pointier, and clocks in at 3,700 fps. It'll go through skin, muscle, and bone from hundreds of yards, and it turns organs into jelly (excuse the crude metaphor). A .22 is a "marksman bullet" for training courses. You can stop a .22 with a cast iron frying pan. A .223, however, will blaze right through a bulletproof vest.
