Sight settings

[Fogman01]

Lumpy those are almost exactly the same numbers as my 45-110 shooting a 545 Creedmoor with 98 grains of Swiss 1.5.
Anybody heard of the method used in the book "The Art of Shooting the Rifle" from 1888? He winds his tang sight down to 0 then shoots a target at 12.5 yards. He measures where the bullet hits and uses one minute for each 1/8th inch the bullet hits low plus 1/8" for bullet drop at 12.5 yards. He has a table in the book that gives the come up for each range to 1200 yards. For example: I shot the target at 12.5 yards and the hole was 4" low. That means I would set 33 minutes for 100 yards. I use 37. I compared it to my tested settings and it worked well to 500 yards but not beyond that. Interesting to see what the ODGs were up to.
