It is possible to make 6.5 Creedmoor brass from 308 Winchester brass, but it is not an exact conversion.

The two cartridges share the same parent case, but the Creedmoor has a different shoulder angle and case length.

The best option for converting 308 Winchester brass to 6.5 Creedmoor is to start with full-length cases and then use a resizing die that is specifically made for the Creedmoor cartridge. This will give you cases that are as close as possible to the original specifications and will help to minimize the amount of work that needs to be done to reload them.

It is also important to note that once brass has been fired in a Creedmoor chamber, it can no longer be used for the 308 Winchester cartridge. This is due to the different dimensions of the two cartridges, and using brass that has been fired in a Creedmoor chamber can potentially lead to dangerous pressure levels when reloading for the 308 Winchester.

Not without a lot of machining and hand-finishing. The 6.5 Creedmoor is a longer cartridge than the 308 Winchester and has a smaller bore diameter. The brass for the 6.5 Creedmoor cartridge is also made to a different specification than the brass for the 308 Winchester cartridge. Therefore, it is not possible to simply re-size 308 Winchester brass to make it compatible with the 6.5 Creedmoor cartridge.

However, it is possible to make 6.5 Creedmoor brass from cases that have been fired in the 308 Winchester chamber by first trimming them down to the correct length and then reforming them into 6.5 Creedmoor cases using either a lathe or a die-forming set.

This process is time-consuming and requires a great deal of skill, so it is not recommended for beginners.

Alternatively, you can purchase pre-formed 6.5 Creedmoor brass from a variety of manufacturers. This is the easiest way to get started reloading for this cartridge and will give you the best results in terms of consistency and accuracy.

You can convert 308 brass to 6.5 Creedmoor brass by reforming the cases.

This is a process where the case is heated and then reshaped to the correct dimensions of the 6.5 Creedmoor cartridge.

The downside of this process is that it will reduce the overall lifespan of the brass cases. So if you plan on reloading your cases, it might be better to just start with new brass cases specifically for the 6.5 Creedmoor cartridge.

Yes, it is possible to make 6.5 Creedmoor brass from 308 Winchester brass, but it is a more involved process than just simply sizing the brass down.

You will need to trim the length of the brass, ream out the primer pocket, and then turn down the case neck diameter to properly chamber rounds in a 6.5 Creedmoor rifle.

However, if you are patient and have the proper tools, it can be done. Good luck!

You can make 6.5 Creedmoor brass from 308 Winchester brass, but you will need to do a little bit of work.

The first step is to trim the brass down to the correct length, and then you will need to ream out the primer pocket so that it is the correct size for the 6.5 Creedmoor cartridge.

Finally, you will need to adjust the diameter of the case mouth so that it will properly chamber in your rifle.
