Making 6.5 Creedmoor Brass from 243

In recent years, the 6.5 Creedmoor has become one of the most popular calibers for long range shooting. Its high ballistic coefficient and relatively low recoil make it a great choice for both competition and hunting. While factory ammunition is widely available, many shooters prefer to handload their own ammo for maximum accuracy.

One challenge when handloading the 6.5 Creedmoor is finding brass. The cartridge is still relatively new, and many manufacturers have not yet started producing brass specifically for it. However, there is a way to create your own 6.5 Creedmoor brass from 243 Winchester brass.

The process is actually quite simple. First, trim the 243 brass down to 1.920” – this will be the same length as 6.5 Creedmoor brass. Next, chamfer and deburr the inside and outside of the case mouth.

Then, using a small base die in your reloading press, resize the brass so that it will fit snugly onto a 6.5mm bullet (you may need to run it through the die more than once). Once you have properly resized your cases, they are ready to be loaded just like any other piece of 6 . 5 Creedmoor brass .

With proper care , this converted brass can be used over and over again , providing an inexpensive way to keep your favorite caliber stocked and ready to shoot .
