This brass is the same as our standard 6.5 Grendel brass except that it has not been formed and has no caliber designation on the headstamp. It should work for most 6.5 Grendel and 7.62x39mm based wildcats. This brass has not been annealed, and will require a body anneal prior to forming, and possibly a neck anneal after forming, depending on how far it is necked down. Wall thickness at the mouth of this brass is approximately .009", which is the same as our 6.5 Grendel brass prior to forming (the walls will get thicker when formed down, and the case will also get longer). Length is approximately 1.550"
*Since this is a basic case, and Starline has no control over how it is formed, we accept no liability and offer no warranty in its use or your inability to properly form cases. Since this case has not been formed there may be more out-of-round mouths than normal.
Our Grendel Basic case can be formed into 6.5 Grendel and 7.62x39 based wildcats such as the .22-6.5 Grendel, 6mm Grendel, 243 LBC and 9x39mm.
* Starline Brass does not sell any loaded ammunition. What you are purchasing are brass cases only and will need to be loaded into ammunition in order to be fired from a firearm.
I use this brass to load for my .401 WSL It is a very easy conversion, simply run the brass through a .41 mag carbide sizing die to reduce the head and trim about 0.050". The small primer pockets are not an issue, 4227 is easy to ignite, very consistent velocities and good groups.
