The B&C reticle is good to about 500yrds as others have stated
but if you have a specific rifle and load you want to use and your
going to send the scope to Leupold you might consider there
blistic plex (They locate the milldots for your cartrige).
You send them your load with all the info,bullet weight and BC,velocity
and drop out to 500yrds and they will burn the retical to match your
100yrd dot, 200yrd crosshares(Zero) 300yrd milldot, 400yrd milldot and
a 500yrd milldot.
You can call them and ask more questions about this system.
I have installed them on custom rifles
with very good results.
Just a thought
