I did a little research on the net for the power factor for each class.
JBM ballistics has a calculator and the results of the load are displayed below with the various associations and what class the qualifies for and what it doesn't. That makes it pretty straight forward. I have a chrono so I'm set for using the .40
I am going to use 165's for the limited and minor and 180's if I want to shoot major.
Now I just have to wait for good weather(spring time here in Montana)
That'll leave a lot of time for practice!!
