If you are new to reloading, or thinking of starting you'll probably want to reload .223/5.56. While you can successfully reload this caliber, it's pretty labor intensive.

Even using a progressive press, there are some steps that still must be performed if you want to create match-grade ammo. Here are some tasks that must be performed to get the most from your .223 reloads:

• Swagging
• Full-length sizing
• Case trimming
• Annealing

Swagging is a process the removes the crimp from the primer pocket on military brass. Not all .223 cases are crimped, but the majority of 5.56 ammo will need to be swagged. This is a labor intensive process that must be performed manually unless you have a very expensive Dillon 1050 progressive press.

In order to chamber and function properly, .223 rounds must be full-length sized. This isn't required when working with pistol caliber or straight-walled cases. Due to the shoulder on the .223 cases, the dies must be adjusted to "squeeze" the entire case in order to properly re-shape them.

Case-trimming is a must for accuracy. It ensures that your bullets will be seated uniformly. All match ammo is carefully trimmed to very precise length. This must be done manually unless you have another expensive Dillon accessories that works with progressive press.

Annealing is a process in which the top of the case is heated to a glow and then slowly cooled. It will look like a blow torch mark near the shoulder of the case. While, not critical to accuracy, it's often seen in military and match cases. The main purpose is aid in proper "stretching" of the case when fired. It also extends the life of the case which is useful to reloaders.

Personally, the majority of my ammo is for plinking. I don't reload ammo for accuracy as I'm usually just shooting steel plates. In my case, I don't trim the cases, and I don't separate my cases by make as most precision reloaders often do. Many of the steps you must perform with .223 are not necessary when reloading something like .45 ACP.
At the end of the day, you should consider how accurate you really want your reloads to be. Of course we would all like to have the most accurate ammo possible; but you must consider the cost of your time as a reloader. At some point, it just becomes cheaper to buy some Black Hills match ammo and be done with it.
