"Hey "shinbone" would very much like to hear about your results with Retumbo & the Barnes 120gr TSX as I had poor accuracy results with that powder in my EW."

Since you asked . . .

This is a Excel graph of my results, so far. Load info is in the title. Two shots averaged for each data point. Thick line is the point-of-impact above point-of-aim for each powder charge, i.e., the basic ladder data. Thin line is the velocity measured with a Labradar. Ignore the squares, as they have little meaning since they are just two-shot "groups." This graph suggests a few good nodes, including one at 65.7 gn, another at 66.7 gn, and maybe one at 68.7 gn. I did not see pressure signs at the highest load, although I am a newbie at reading such things. Next step is to shoot different COALs at probably 66.7 gn.
