Keith, you are in the ballpark, maybe.
I had best results at 13.8 of Blue Dot loaded to the lands, with IMI military brass.
Have a Blue Dot load for my BR which is 14.4. Someone here whipped me straight after some Fireball problems, the "general rule" seems to be to take your 22 case, fill it up with Blue Dot to the top, then figure 60 percent of that will be maximum under 40s.
All of you who haven't tried Blue Dot, be advised that it's a great load, but it's full-pressure and the difference between "perfect" and "oh, DARN" is pretty small.

Down hills fast
Tonnage first and
Safety last.
