Love my Grendel...mine has a 24" barrel and is a hammer with pretty much everything I've tried in it. It shoots particularly well with the 120 Nosler BT, 123 ELD-M and 95 grain VMax. Like JTD, I've had the best results with XBR8208 and AR Comp. I was able to pick up a pile of "pulled" 120 BTs on "another site" (Sorry Wes!) at a price that pretty much makes them "cheap plinking bullets".
