SCR, Do you have any other calibers where load data using XBR 8208 is available? I myself purchased an eight pound jug of XBR in preparation for my Grendel. After making several attempts to find a "good" load using XBR in my rifle and only succeeding in ruining brass, I gave up and use it in loads for several of my friends .223s. It is a fantastic powder in long and short barreled .223s and shorter barreled Grendel ARs (other forum members have had experiences similar to mine with 24" barreled Grendels).
Did your rifle cycle reliably with that 26.5g load?
