I think you need to figure this out on your own!

In the 13 pages of 308 load data it's in there.

Or you could set up a 4' cardboard box at 100 200 300 400 and put a marker to it then run some chalkline across. Shoot about 5 times each distance. Take your drop measurements with a caliper. Jbm it and there ya go.
