After reading the MK316 thread I decided to work up a load for a 26" barrel. I believe that OCW is tied to OBT so barrel length matters. The MK316 load consists of a 175SMK and 41.8grs of IMR4064 in a Federal case and primer at a 2.800" OAL. I believe this load is optimized for a 24" barrel per my QuickLoad calculations. It also prints to the left if my point of aim in my 26" barrel.
So I optimized the load for my 26" barrel and Winchester cases using OCW/OBT and QL. According to the software the optimum load is 41.5grs of 4064. I loaded five batches of three rounds for three different primers: 41.1, 41.3, 41.5, 41.7, and 41.9grs of 4064 with FC210M, CCI200, and WLR primers.
It looks like QL is right on the money with the 41.5gr load.
