Underclocked ... that's what happens when you just have to push the envelope. It happens to me all the time. Still, that is some real nice shooting. I think I am going to try the using the scale on a few of the next loads. I want to try some 65, 70, 75, and 80 grain loads that I will weigh out. I really think I can make that big hole you got there appear with my Ultra Mag.
