in my experience...
the BDC o Ballistic plex is most useful only with factory loads, my
"precision" loads dont always match the drop on these reticles.
my 3006 with winchester powerpoints 150 grains (gray box) matches beautiful the ballistic plex on my burris, but I still can`t match a load to the BDC in my 6.5-284 long range rifle!!!!
the loads that I have developed for this rifle(6.5-284) that nearly match the drop on the reticle shoot poorly.
by the way, how much drop is in the BDC reticle?
In the burris ballistic plex the drop is: 0 @ 100 yards, -3 @ 200, -13.5 @ 300, -30 @ 400 and -55 @ 500 yards.
Dont know if the nikon is the same!!!!!!!
thats my experience...
