I think this diagram is to demonstrate the trajectory as the three drawings are at 100, 200 and 300 yards.

Or…..I’m also confused;) Actually I probably am confused.

The hold on the 300 yard diagram doesn’t look nearly high enough to correct a 27” drop to me.

Elmer Keith wrote about taking fine beads, out of the “V” beads etc. It’s hard to make sense of it without doing a lot of shooting with iron sights, which I would like to do.
