I am just about finnished a 6.8 AR. Just waitng for a Magpul PRS stock. It has a White Oak stainless match grade 1/11 twist barrel with a mid length gas tube. The upper is a left hand Stag Arms receiver on a Stag Arms lower. The front grip is a free float 4 rail Yankee Hill lightweight assembly. Has any one come up with an accurate load for 115gr bullets? I want to try a couple of different powder combinations to find what is best for this system. I am having trouble finding current information on the web.
