I'm still reading a lot, in prep for zeroing my 30-30, and I got to thinking about bullet-drop. So I started searching and found the info that follows. I'm a pistol shooter, so I don't know if this will be helpful to anyone here- you all may have 10 of em already- but thought I'd share since I found this. Hope it helps somebody.
