I have been having issues lately with efficiency and I am trying to figure what is going on. I have been ordering from BMW and am just wondering if anyone else thinks their mill might be the problem. I am not trying to say anything bad about them I always order from them and they have great customer service. I am just wondering if I should have them run the grain through their mill 2x or if that would just cause more problems or if I need to search deeper for my efficiency problems.
