I've been looking at Swarovski scopes and to be honest I don't think the information is very helpful. I have a couple Hawke scopes which are parallax adjustable but I don't really know a lot about it. I'd turn the front end until the picture is clear and it would indicate the range. On the swaros it appears to be a turret on the side. I'm assuming it will do the same thing but does it shift the point of aim as well? Can anyone with some practical experience give me an idiots guide?
