Quick check of my work
Bore sighting with a laser and 17 yard target. 243 win. with 95 grain Winchester ballistic silver tips. For a 100 yard zero the hold over is? I get a smidge over 1 inch. What say you?

It all depends on your horizontal scope cross hair height compared to bore height. The bullet will cross your line of sight twice on the way to the target. The only way to know for sure is have absolutely accurate info on the bullet drop at 17 yards from a perfectly horizontal barrel and factor in the distance from bore center to horizontal cross hair. My WAG is at 100 yards you will be off by 3-4", windage is an unknown depending on twist bullet weight and stability. With that said, you will hit paper and adjust from there. 3 -
No clue but with your math skills I'm going with just a hair over 1 inch.

Hold UNDER. 1 inch low @ 17 yards would yield a ZERO @ 100 yds 3 -

Thank you. I appreciate the correction.0 -
Yes, at 17 yards the bullet is on the rise. It has been said what you get at 25 yards is the same at 100.Might be , might not. shooting at 100 yards will tell the truth.

I have calculated and calculated but generally I get surprised when I fire a few down range. And that is where the most fun is generated.
I built 5 AR's during the Covid lockdown and after they were completed I took a couple days off from other projects and sighted them in. Different calibers and barrels and sights.
It turned out to be the most enjoyable 2 days I have spent in a long time.
From what I read above I think your first shot is going to be well on the paper.

If I remember correctly,we sighted in M-60 machine guns at 660 inches and they would be very close at 660 meters. 6
