I like the Grendel because of the size options, and because in the Rifle it can shoot almost anything I want withing the ranges that are practical for me. However, I am building a Creedmoor upper to go with my AR10 lower that I already have. I put together a handgun every year for a handgun hunt, the last two years being the 6.8 SPCII, a 6.5 Grendel, and since I'm going to need to take a long shot at a Mouflon later this year, I am putting together a Creedmoor handgun. Since I already have an AR10, I will build a Creedmoor upper for it. I have .260 Rem, and .260 REM Ack Imp bolt guns, and have put down a lot of animals in Africa with them. The 6.5 Creedmoor was created, and correct me if I am wrong, because while using the longer bullets in a .260 Rem in an AR10 frame, there is a magazine clearance problem. So the front end of the cartridge was shortened .115 inches to allow use of the heavier bullets. The shoulder was also changed from 20 degrees to 30 degrees. This makes the difference in case capacities from 54.8 gr water in the .260, and 52.4 in the Creedmoor. I would go with the Creedmoor because of the better .308 magazine clearance.
