Re: Using laser bore sighter and Burris offset inserts
I do it in the evening and laser the garage door across the street. It's exactly 100 yards away and works well. At only 7 feet I'm not sure you can figure out much based on my results.
FYI, I've also done it out the basement window at something 20-30 yards away and while not as good as 100 it's far better than 7 feet.
