Laser Boresight and Ballistics Question
If I was setting up a scope for a rifle and I used a laser boresight, it would help my windage, no doubt, but what about ballistics? For example if I have a 300 win mag and I use a laser boresight to 200 yds. The bore sight tells me where the barrel/bullet is pointing and if I line my crosshairs up with it, the bullet should hit low because we have not yet accounted for gravity. Thus I would need to have my crosshairs about 8" below the laser dot at 200yds given the speed of a 165gr Win mag.
Am I off in thinking this way? (and I know it is best to actually shoot to sight in, but I am just looking for insight on this particular subject)

I use a laser boresight at 25 yards, but just to get on paper. There are a lot of things that are going to affect the bullet down range, and a laser bore sight doesn't account for them. Stated ballistics may work for some firearms but often they don't. I'm a believer in shooting at the range I think I might have a maximum shot at when I can.

Ditto what grizzlyman said. Boresighting is just to get you on paper. Heck, I've sighted in dozens of rifles over the years - never boresighted any. Not really neccessary, but if you have one its obviously good to use. Only way you are going to know where any gun shoots is to shoot it.
