Wish I had more to play with. No chrony data yet. Maybe  next time they will get a chronograph. Both loads have been posted else where and I tried them on a whim. The node for Lever and 103-108 have all been around 29 gr for me and others so start a little low and work up. I haven’t played with CFE much but it’s very similar to Lever. 18” BA barrel with RLGS and std block for reference.
Thanks. I will have to check my measurements again, but I originally got my max COAL at 2.254" measured. I normally start load development by starting CBTO .015" off the lands, but was going to start at .010" with these and testing for OCW for low SD/ES first. If my measurements were correct, 2.275" would be way too long and in the lands. 24" McGowen with AGB. I do see Brownell's has 105 Bergers in stock, but since I have just ordered 500 107SMKs(already have 200), I will hold off and get the best I can out of the 107s. Will update when I get Chrono data(Magnetospeed).
