I remember years ago trying to bore sight rifles to get a new scope somewhere on the target. It involved steadying the rifle in a padded vise and squinting down the bore at an object out across our back yard and adjusting the scope on that object. Talk about a pain in the butt...
A few days ago, I did it differently and entered the 21st Century with its bag of technical tricks.
I recently acquired a very nice Ruger No. 1 single shot rifle chambered in 30-06, vintage of 1981, scoped it, and bore sighted it without the trouble of a vise or trying to make out a tiny spot on a wall looking through the barrel. I found this device on eBay; it cost about $8, and it turned out to be a neat way to bore sight.
It's a bore-sighting laser in the form of a cartridge case. This one will handle 30-06, 270 and 25-06. It's simple. Unscrew the base, insert the 3 tiny batteries. Presto, a laser beam is generated. Chamber it in the rifle, and the beam, centered in the bore, is projected wherever you like. No need for a vise. I adjusted the scope to line up on the beam laterally, and to place the cross-hair a bit above the laser dot, allowing for the parallax distance of the scope over the bore.
On the range the next day, I was right on a 50 yard target, and the adjustments were easy to sight it in further at 100 yards.
I recommend this gadget highly - if you are still doing it the old way, an investment of about $8 will serve you well.
