If it is the NNY headstamped brass from wolf gold ammo then the brass is top notch, and yes, I would certainly recommend reloading it. In Grendel I would bet that is what it is. It is all I use in 6.5x55. That said the rim is usually thicker than other brass and you may have to improvise in finding a shellholder to hold it properly. The only problem I have had is it slipping through my shell holder when sizing due to the thick rim, and having to use a larger holder. Good case lubrication has solved this.
