Using the 175 SMK w/a muzzle velocity of 2800 FPS, sighted in at 100 yards, it drops 30.5 inches at 1000
That has to be a typo. From a 100 yard zero it would likely drop close to 30 inches at 400 yards, never mind a thousand.
At 1,000 yards I'm sure drop from a 100-yard zero would be well over 300 inches.
You're right,that should have been "30 MOA".
