Which Bore Sighter?

I will say that I’ve never used an official “bore sighter” but the following works well enough for me:
I just mount my rifle in my tripod (or any other sturdy rest), pull the bolt out and look down the barrel at the target and then without moving the rifle - adjust the scope so the scope and barrel are lined up together on the target. With this method I can usually hit a 6inch shoot n see target at 100 yards and then be zeros in 2 additional shots or so.

I’ve been using a Bushnell optical boresighter for more than 25 years. It has always given me good service. With that said, if you remount a scope using a boresighter, regardless of which type you use, you’ll need to verify the zero with live rounds.
Understood. Just hate starting at 25 yards just to hit paper. It would be nice to use a bore sighter to hit paper at 100 yds. At that point, I can get it to POI within two more shots.
On a bolt gun, it's not a big deal to pull the bolt & look down the barrel. On the AR, not the end of the world, but have to separate the upper & lower. On some other guns (pump, 10/22, etc.) not possible to look down the barrel.
Another thing I like about the Bushnell is that it uses a grid for collimation. This not only allows me to get the rifle on paper, it allows me to record a grid position for each rifle/scope combination and verify zero in the hotel room after traveling, or anywhere firing live rounds is not possible, or practical. You could do the same thing in your situation, with multiple zeroes on each scope. It also gives a visual confirmation that the turrets are tracking normally. I don’t know if any other brands use a grid, and if you decide to go that route, you probably need to verify that Bushnell still does, as mine is pretty old.
I've always done it the way that Sogan mentioned and it's never taken more than 3 rounds to go from New Scope to Zeroed.
The Sweany "Site-A-Line" bore sighter by the Alley Supply Company. My unit has the diagonal cross hairs. Excellent tool. Only drawback is having a separate spud for each caliber.
