OK, I have an M1 4.5 x 14 scope. It's mounted on a 20 MOA base. I sighted it in and re-zeroed the turrets. On the elevation turret I have 3 of the hash marks showing. Does that sound right, or is there a way to re-zero the turrets so that only 1 hash mark is showing so I don't accidently go back to zero for example with only two hash marks showing and then my POI is off? Do I just need to remember that I always need to see 3 hash marks to be sighted in at 100 yards? I miss the simplicity of the M3. Thanks.
