I use a bore sight often...
It works great to dial in the horizontal....
Of course, you will need range time to dial in the vertical...
Where it really helps me is that I can record zero on a target sheet, and re-check zero when I travel...
Nice to know that I can get it dialed in if a scope gets damaged, battery dies on a red-dot, or fixed sights get damaged...all of these have occurred to me over the years...
