For the price of a box of bullets, you’ll never waste ammo getting a rifle on paper again.
There are many ways to bore sight a rifle. This $30 laser from Bushnell is my favorite. It comes with shims for .22 to .50 caliber rifles and 20 and 12 gauge shotguns. In-chamber lasers might be more accurate, but I’m not looking for my first shot to be a 10-ring. I just need the first shot on paper and this has never steered me wrong.
Watch the video for a shockingly simple demonstration on how it works. The further you can push the laser – to 25, 50, or even 100 yards if light conditions allow, the more accurate that first shot will be. For the price of a box of bullets, you’ll never waste ammo getting a rifle on paper again.
