This boresighter works pretty good,  if you put the scope right on center with a 22Lr or equivalent youll be almost centered,  I used it on my sks and the the sights have to be just a hair above center line to hit a 6 inch circle at 100 yards,  I also used it on 3 mosins, one of them with a scope, I had to put the scope 4 squares above center to hit target, the other 2 mosins have iron sights and those got set at 2 above and the other one at 3 above.  Its a little tricky to use at 1st, but it works, and its fairly good for getting on paper, I used it at the range, which was nice to help get on paper 1st.... when I sighted in scoped mosin on center line it hit high at 100 yards, (like 14 inches) so I went 2 squares up from center at first, then shot, still high but better, then went 4 squares above, and made 6 shots in 6 inch circle at 100 yards,  the rifle was rested with sand bags and I barely touched the gun to fire, just to pull trigger and just having my shoulder against it. I am happy with it, when using it just don't let it shift around in bore., the arbors work ,but still be careful,  It will not work on any raised scope like a AR 15 or M4  so keep that in mind  My thoughts is if its a high powered round go up from center 1st,  if above you shoot low if under center you shoot high,,  for me center line only worked on my 22 lr rifle,  bring it with you to the range and get on paper. vertically I had no issues with left or right with my rifles......kinda wierd
