Home Forums Hunting & Shooting Ask The Gunwriters Wha is a good ,inexpensive boresighter ?

Indy,

Maybe I went on a little too long. Let me put it another way:
The main virtue of a bore-sighter is in mounting a scope correctly, plus testing various scope functions, not in sighting-in a rifle.

That's exactly what bcraig wants one for.

This thread had some interesting posts, John. A story.

I was an armourer in the air force. One of my jobs was to boresight fighter jets. We usually did this after changing or repairing a 20mm gun. We used a target board inside the hangar which was put precisely 1000 inches away from the muzzle. We attached an optical boresighter to the gun (stuck into the muzzle with a spud) and ratcheted the gun mount so that the boresighter (and, by extension, the barrel) was aligned to the target board at 1000 inches (or 83.3 ft or 27.8 yd).

Next, the plane was taken to a harmonization butt. This is a 25 yd range with the backstop built into a hill. The aircraft was jacked up, off the ground, chained down and 25 rds were fired at 25 yd into a target. Any further adjustments were made at this time. When it grouped correctly, the gun was deemed to be sighted in and a pilot would take it to the range to fire at a ground target.

So, we boresighted the aircraft gun, shot it at short range to ensure it was aligned and then gave it to the driver to verify at a longer range. Shooters can use the same procedure when mounting a scope, to ensure everything lines up. A quick operation that can save a pile of frustration at the range.

Bought one of the Wheeler products w/ green laser; not inexpensive, works well.

I'm still about 2/3 confused about its function. I should probably buy your book and read it.
