I have a leatherwood m600 scope. not the best but it works. went shooting today and at 50yds i was shooting about 1/4" to the right. I then moved to 100yds and shot. I was shooting 4 1/2" to the left! what is going on? I have no idea. Could you guys tell me what you all think? thanks
Ok i talked to someone back at the range and they said it could be due to parelex (SP?). Does this sound right? I dont think so because I have not had this problem beforewith other scopes. I shot again at 50yds and it was again back to shooting 1/4" to the right. Moved to 100 and its shooting 4 1/2" to the left. Could it be a defect in the scope? I hope not because i dont think I can send it back. I bought it over a year ago before I went to Iraq and never shot with it untill now. Any help out there?

When you say the POIs went from 1/4 inch off the right to 4.5 inches to the left, it's still in a group?

While it is possible that parallax could be the cause, it's not that probable going from 50 to 100 yards. I would expect a parallax error of this magnitude with a scope zero'd at 100 yards, but being used to hit something at 25 yards, and not the other way around.

If you have a collimator, mount it on the rifle after ensuring that it's unloaded. Then, just do a box test and see how well it can follow the squares on the grids.

Were you able to adjust it so that you were hitting center?  

The parallax can be an issue but most likely not that big of an issue at 100yds.
