Reloading 223 Remington and 5.56 NATO ammunition is essentially the same as loading most other bottleneck rifle cartridges. You will use the same press, powder measure, shellplate or shellholder, and so on and so forth. Reloading dies are the same for 223 Remington and 5.56 NATO because as we’ve already discussed, the exterior dimensions are essentially the same.
