you know what a lazer bore sighter is good for?? setting up a chronograph. I just take a target and put it behind the chrono and its a snap, just remember to take it back out.
as for sighting in the scope forget it. I have one of the old school bushnell bore sighters that uses the different size spuds and you can see a grid, this would work great sometimes and others I would totally be off the paper. I have a house behind me that is about a 100 yards away one of the lights on the side of the garage works great to line up with bore with and then the scope, this is mounted in a cheap lyman gun vice. works great everytime.
