Both are great guns and I've really grown to like the 6.5 Grendel cartridge. I shot 3 cases of Hornady Black to build up a stock of brass and just a few weeks ago started building up some loads for the 18" using the Hornady 123gn ELD-M bullets. So far I've used 8208, AR-Comp, VV N540, and CFE 223 for powder. It appears that the AR-Comp might be the best powder. There's a few more powders I want to try, then I'll start working with some other bullets. To date, I've just been killing paper working on getting the guns functioning (adjusting the gas), sighting the scopes and building up a brass supply.
