"SWFA, thanks, but Brownell's has it for $69.60, $20 more than what you said. I would be most appreciative if you can tell me where to get it for that price, or at least closer to your price than Brownell's."
SWFA is a scope business, he was quoting you his price on the item:

I have spent a lot of money with Chris.
The best way to get on paper if you don't have a boresighter is to start off close. If you don't hit the paper, move closer until you do. Then you can see where you are hitting. I almost always start off at 25 yards, fire a few shots and get it pretty close, then move back to 100 for the final setting. Over the years I have found that this saves time, ammo, and frustration over hopeing I will hit paper at 100 right off the bat.
"One last reminder makes sure that the bore sighter is out of the gun barrel before firing. "
Another beauty of the laser boresighter I was using; the laser itself is like a cartridge. It is chambered in the gun. It would be impossible to load a live cartridge with the laser in the chamber.
