hogrdr & HuntHard,
I didn't know the Nikon Omega scope with the BDC-250 reticle was setup for any load, all it talks about is the 150 grain charge with 250 grain bullet, and I thought if you do anything different is will not work. Maybe I am wrong, that's OK no problem.
In my opinion, the ballistic reticles all make sense on paper from a text book and shooting rest, but from actual real hunting environment its not practical.
Distance doesn't matter for split seconds decisions, but there are so many variables like safety, wind, weather, terrain, how many eyes or ears and now finding little circles or lines before you can shoot.
I concentrate on my breathing, trigger pull and shotplacement all at the same time, it's just too easy to select the wrong circle or line.
If people like ballistic reticles that's good, I have had unsatisfactory hands on experience with them, so I choose to use regular scopes which works for me.
