I received my new powder measure the other day. I was able to load 10 grains of 3f with the .310 patched round ball and was pleasantly surprised to have all of my shots hit in a nice tight group with the balls practically going through the same holes. Only issue is that they are still hitting high, about 2 1/2 inches. No matter how I seemed to place my eye on the sight. I have order a new front sight that is 1/2 tall so I'll have plenty of adjustment room. Hope to have her ready for the squirrel season.
