Without doubt the BRD bug has bitten me hard.

Until today I was clearly of the impression that an outbound 25 m zero would reacquire the zero mark approximately 300 meters out, pending round specs and external variables. I'm confused because I do not see anything approximating that relationship in the most of the ballistic charts in this thread. What am I missing? Send help.

Thanks,

Michael, a/k/a Doc
Here is a chart showing the 33yard zero...the 25 would cross even further out.
