I didn't read far enough ahead.
Bore sighting lets me get beyond 15 yards to rough in the scope.

Smart man! I find many of today's rifleman cannot compute trajectory for calibers either from 15 yards to whatever.
As long as you get there. Just a different way of doing it.
I still prefer to pull the bolt and sight it in. The reason being I'm at a range, and the round will go beyond the target and go who knows where when I start out that close.

So you can't put the target against the backstop or do you use a fixed bench at 100?
Interesting thread.
I have a process that includes the fancy light. I have done it other ways but the light I have works well if you use it properly.

Yes, but you’re wrong. Wrong, wrong, wrong.
By now I am very used to it.
But I am always open to a new way of doing something.
Oh yeah, you’re married still!

Yes and swimming in a sea rich in estragon.

I use the Jack O'Connor method to bore sight & takes three shots
first-
scope mounted 1.5 in. above bore use 25 yds
iron sights use 12.5 yds
reason: almost ALL centerfire rifle cartridges are "dead on" at that distance and at 100 yards. this is good fact to remember for ever....
bore-sighting sounds technical BUT is very EASY
you are just looking through the rifles bore just like a drinking straw if you will.
bolt guns & ar & single shot are easiest
lever guns take an inexpensive mirror (I have one designed for this but could get a glass/mirror shop to make one) they are thin and fit in the open action so you can see through the bore.
For a target I use any object size of a brick @ 25 yds or 12.5 yds
Bench or table with any box & soft towel to rest gun and allow you to see through the guns bore and align it stationary while I adjust scope cross-hairs
that step takes some skill but is easy
you look through the bore & center the brick
then without moving the rifle move scope elev. & windage dials to center of brick
Success
then ready for live ammo at 25 or 12.5 yd range
ALL BORE-SIGHTING IS DONE @ HOME in comfortable setting
I shoot just one shot @ my favorite target plain white 8.5 X 11 black Quarter bull
a quick adjustment is made using the graduations of the scope 1/4" usually at 100yds is standard
key is that at 25 yds you need to go 4 times that much ( 1/4 " requires 4 clicks at 25 yds and 1" takes 16 clicks to change the impact point.) such is the math that scares a lot of people
2 & 3 rd shots taken at 100 yds if available. otherwise you need to know the trajectory of your cartridge for say 50 yds.
If you noticed I did not take a 2nd shot at 25 or 12.5 yds. because most scopes today have rather accurate adjustment graduations at 100yds
Using the same target or new one at 100 yds fire shot 2
measure or calculate to get shot 3 to where you want the "zero"
I use + 3.0 inches for big game and + 1.5 in for varmints
Try it you should now be ready to bore-sight with confidence.
good shooting

The wise will have seen that these threads are purpose driven thought starters especially for folks that haven’t given their sacred cows a second look. It stings us all sometimes when our ideas are tested. At the end of the day however, we expose the knowledge for what it’s worth. There is really no right or wrong, good or bad equipment per se but how it works for us and why it does.
youre welcome
I also do all my own optic installs, and use bubble levels to ensure proper mounting. Usually a quick boresight through the barrel (if bolt removable) and/or use of my universal laser tool: https://sightmark.com/product.php?item=312
My neighbors garage is about 30y, so it serves as a starting point before I even leave the house. Usually puts me within a few MOA so fine tuning is a breeze. As stated above, the primary reason is to save on ammo. I grew up on the "3 shot rule" for sighting in, but this makes life a lot simpler.

I used the scale on Google maps and found I bore sight at 75 yards. I'm thinking the shooting range is 75 feet, not 75 yards. But I'm in the target when I get to the range.
I have a vice on a round steel tool table. I vice up the barrel in some padded jaws and center the porch light across the street through the barrel.

No one uses the "one shot" method anymore? Only tools you need are a few sand bags. It's been around forever and used to be the standard.
First reference I saw to it was from the 60's ish and I think it was from guy named Jack Connors or O'conners but I could be wrong on the name.
Easy, fast, and doesn't require much equipment.
A google search brings up a lot of guides for doing it.

I have boresighted a rifle, fired a round and had it shoot dead on more than once. The problem with that is it was only one round and one round isn't enough to tell you anything other than you are or are not on paper.
