use the crono.
for open you want to use the lighest bullets you can with the most powder (to work the comp) until they go fast enough to make power factor. Open in the one division where it is normal to go over the power facter (I load 9mm to 175ish pf). You are more looking for the dot to stay in the glass and track correctly than what feels soft. My gun is really load but I dont even notice the recoil because it is more straight back into you hand and not as "flippy" like non comped guns. If your new to open (I am) I would find a load that works well, makes pf., and works the comp and then not worry about the load for awhile. There is so much to work on before the load is holding you back.
Im not familiar with your powder where did you get the load data from?
