I just loaded and shot some 129 Hornady IB's over Re-33 in my 264 WM, and, when I got home, I compared the actual chrono'd velocities to QL. To get an exact MV match, I had to lower the weighting factor to .39 (the QL instructions say an overbore bottleneck case would have a .33 default value).
Has anybody else adjusted QL for the 264WM?
