Sighting in a new scope

[DeanMk]

Never seen or heard of it being done this way before, but am wondering how well it would work?
Does anyone here have any experience with this?

Variation on bore sighting. Have done this minus the 'deprimed' brass (kind of a tiny hole for old eyes). If you can remove the bolt and see through the bore it works.
This can be done at 25 or 100 yards.
Remove the bolt.
Position the weapon on a stable platform.
Align the bore to the desired POI.
Adjust the scope (or sights) to the bores POI
Assemble the bolt and take the shots (3x, don't trust a single shot)
Fine tune if needed.

I happened to have 25 yards in my back yard. A table with a rest and chair. And a full size poly cone with a white top. Set the gun in the rest and adjust it so you can see the white top of the cone down the bore. Then look through the scope and adjust to see the white cone top. When I got to the range it was almost dead on centered and 6" high. About 12 clicks down and a couple or three left. Bingo! Same basic thing. If I do it again, the unprimed brass looks like a good idea too.

You can get one of these cheapies (LaserBoresight) and align your scope down a long dark hallway.

I had bought a used Bushnell Laser Bore Sighter from a member. It worked fine, but was more difficult to set up the the method above. Now though, the cat loves it!

I'd think that the method in the video may not work so well for small bore rifles.

I've been doing that with Berdan primers for years.

Had to think about it for a bit. Good one!

I boresight all of my rifles like that minus deprimed case- that may be more precise but is probably harder to find your target.

I could watch her zero in a scope for hours, lol.

 

[bionic knees]

swap ped scopes on my short mag recently and used one of these, haven't shot it yet so I don't know how well it worked.

Not sure how well her eyes are protected with her safety glasses on her forehead.

I've done it many times. One of the many things those scary, crazy FUDD RSOs at Tri County have taught me.

 

[DeanMk]

Good to know this, or at least a similar version, method does indeed work.
Thanks for your input everyone.

Are you trying to impress me? Deprime rimfire ammo. THEN I'll be impressed!

Dean, do it without the brass case.

1. I'll hang a florescent line at 21 yards in my driveway with a bead tied in it, and use a gun vise.
2. Level the rifle
3. Mount the scope
4. Align the vertical reticle with the string line
5. Tighten the scope, keeping level and alignment
6. Center the bead in the rifle barrel.
7. Move the reticle to the bead.
8. You'll be in the black at 100
9. Same vise on the shooting bench, focus on a 1/2" dot on the target.
10. Take one shot.
11. Because of recoil, move the reticle back to the dot and make sure the rifle is anchored.
12. With the vertical and windage knobs, move the reticle to the last shot hole in the paper.
13. One or two more shots to confirm.

Eyes? What eyes.

Thanks, I'll keep that in mind

Have done this minus the 'deprimed' brass

Ditto this - and have done this all my life. Brass not necessary - bore diameter is plenty small enough.

Last time I did this my first 'live' round was 1" below the bullseye at 50 yards!

Please tell me the highway is BEHIND YOU. ( Thanks, I'll keep that in mind).

The bolt is out of the gun.
Where I am, you cannot see me in my garage when I'm doing it.
And yes, I'm facing a stone wall across the road.
