I'm thinking about building either a 6.5 grendel AR upper or a 6.5x55 savage/stevens rifle build. Maybe both eventually, but for now I want to focus on one. It will be used for long range target shooting and hunting. I like the semiauto AR platform, but quality grendel barrels are hard to come by and usually associated with a long wait time. It would be easier to find parts to build the bolt rifle and brass is cheaper/more available for 6.5x55. Not to mention, I already reload for some swede rifles. Decisions decisions.
