SWAGing this:

IF you assume the laser (and the bore are level) and you set the dot on the laser at 50, the bullet should impact ~1" low at 50 yards, ~4" low at 100 yards.

IF you set the laser 1" over the dot at 50 you should be ~ on at 50 and somewhere between on and 2" low at 100?

Again it's to get you on paper So you can dial it in with the ammo at the range.
IF you dialed it so that the laser was between .75" and 1" high at 50 yards and you aren't on paper at 100 then you are probably using Chinese ammo...or the scope mounts are crooked.

I think I've got everything for a .308 build AND a .243 build except the gas block for the .243.
I'm considering putting them both together for a single lower and IF I do that I might want to use a PRS stock. IF so I'll need to get that also.
