Sighting in a new scope on a rifle or slug shotgun can be an intimidating chore. You probably imagine yourself spending an afternoon at the range, shooting up a box of ammunition, and returning home with a sore shoulder.

Believe it or not, you could probably zero in your scope with just six shots or less.

The most frustrating part of sighting in a scope can be just getting your shots on paper. If you don’t know where your rifle is shooting, you don’t know what adjustments to make.

You can eliminate that aggravation by using a collimator or boresighter, an optical device that enables you to put your bore and scope in approximate alignment. Collimating your rifle in this way probably will not put your bullets in the bull’s-eye, but it will put your bullets on the paper.

Boresighters are available from several optics manufacturers, including Leupold, Bushnell, Cabela’s, Laserlyte, and Simmons generally in the $69 to $200 range.
