Okay, I am not a bad guesser!
The needed info is on the print - thanks. The nose is 0.65 of a caliber.
"the width as it drops with 1:20 is .443, the width in the below drawing is listed as .451"
Sorry to confuse. One way to talk about and understand nose lengths is to describe them in caliber.
You may find it somewhat challenged for "300 to 600yds". compared to other bullets you could use.
