## Rise of the 30 Caliber

00:51:59 | This is perhaps the most important non-ballistics chapter in Applied Ballistics for Long Range Shooting. Sights and their adjustment are the critical bridge between calculating an accurate fire solution and applying an accurate fire solution. Bryan and Mitch discuss the nuances of tall target testing, and scope levels, and recount many experiences where having control of sights made all the difference.

Noob here… so unpacking my understanding

30″ = 30MoA (1″ per MoA) = at 100y = 10mill = 10cm (1cm per Mill)

For the tall target test, on a MRAD scope, 100 yards. comment on plan, say 4 steps up, each say 5 mil (50mm) up per line, 10mil right, down and across again ?

Fitting nicely still on a A4 page

You can definitely do a test like that, but your dimensions are off. 1 Mil is 1/1000 of the distance. So at 100 yards (3600 inches) 1 mil is 3.6 inches. If you were operating in metric, say at 100 meters, 1 mil would be 10 cm. So you need a 36+” tall target in order to test 10 Mils of adjustment. Hope this helps!

So you all talk about measuring exactly 100 yards from the target. Because of the word exact I got to thinking about where exactly you measure from. Is it the front of the optic or the end of the barrel?

Thank you
