I have recently started a 6.8 project (the lower is fully assembled) and I am trying to find the cheapest of the 6.8 ammunition out there, can anyone who shoots 6.8 help me out with this one? I am just looking for some of the cheaper stuff to put a few rounds down range when it is complete, however, it will be more of a hunting AR, so I will also be investing in some of the more expensive stuff too.
