^^watch video here^^

As a budget oriented shooter and reloader I am always looking for the most cost effective ways to shoot more. 300 Blackout is one of my favorite calibers due to its diversity and enjoyment level however it's biggest drawback is cost. Even for a reloader it can be a costly caliber due to the more expensive 30 caliber projectiles and price of brass.

300 Blackout was developed from the .223 Remington cartridge and aside from the bullet diameter the cases are the same in many ways. The Blackout is basically a cut down 223 case necked down to 30 caliber. A common practice for Blackout reloaders is to convert 223 cases to 300 BLK. Thankfully there is no shortage of 223 or 5.56x45 brass and with a couple affordable tools the process is fairly straight forward.
