Rifle Scopes nightforce clicks accuracy

[George63]

wanted to test the clicks/vertical travel on NF BR scope so I set up on a reliably measured 100 yd range and shot 2 groups using the full available adjustment

checked the group centers with a level and the vertical travel looked good, but when I did the math the travel distance was 1/2 of 1% to much, I was hoping for a little better. Looking at how I was set up the muzzle was just over the 100 yd line but that puts the reticle 18" beyond 100 yds - or 1/2 of 1%

so I slid the rifle forward until the turret/reticle ( where the angle is actually adjusted from) was at the 100 yd line and shot 2 groups again, this time it came out within .1 inch of the calculated spread or 1/50 of 1% (much closer than the group centers could determine for perfect)

so I am going to say the NF click values are as perfect as can be measured

if you do this test in MOA remember 1 moa is 1.047 inches per 100 yards

the math is much easier in metric/mils - .1 mils is 1 centimeter per 100 meters

1/2 of 1% is not much. You could easily be off that much on your distance from the target unless you used a known accurate tape measure. Lots of ranges are off a bit. One percent is all you can expect IMO. In 25moa of elevation 1% would be one, 1/4moa click.

Your shooting could be off too. Are you sure you can shoot sub 1/4" groups? 1/4" at 100 yards is about 1% of 25moa box test. What if your group is off 1/4"?

The only way to really check the accuracy of the clicks is to put it in a sturdy rest and aim it at a known spot. Adjust it and see where the reticle is after you adjust it. You should be able to measure it pretty close by using grid paper and watch through the scope as you go through the clicks.

you did not read the whole post, after moving the rifle forward 18 inches so the reticle was at 100 yards instead of the muzzle, ( the range is recently built and laid out with precise surveying equiptment) the groups measured within 1/10 of 1 % of the calculations, so perfect click values
