I'm on a 6.5 Grendel based forum on FB and in my experience and many others on that page, is that with a 123gr bullet the GO TO powder for accuracy is IMR 8208 XBR. Several guys on the page all are using 27-27.5gr of 8208 and accuracy has been good for several different people. In fact it's one of the top "pet loads" on the FB group for guys that want an accurate load easily with no fuss and no muss.
