I think (weaver?) had a recticle with a similar concept back in the day. As i recall it had a darker duplex with multiple fine lines horizontal and verticle that formed boxes. Its been ten years since I looked through that scope, but as I recall it only had a few lines, maybe 3 each way. those that used it really liked it.
Bullets have well documented performance specifications.
Min Velocity info is available, and describes the performance floor of the bullet... DON'T allow yourself to reference F.P.E. as an accurate descriptor of killing power.. You are smarter than a copy editor, and you understand that you can determine maximum (reliable) effective range by comparing your drop chart to published bullet data....... And, dog-on-it, people like you!
