Re: JBM calculations

If you are asking if JBM works well then the answer is yes. Very well actually if the right info is put in.

I used it with FGMM in a 700p and it worked well out to 500 that is as far as I got. I think if anything it gives you a great starting point and you could at least use it to get close on paper at all the distances you put in

One day I want to be as smart as Lindy

Also, JBM works pretty well for me and I just got Bryan's book this week. Very interesting stuff.
