Re: What causes horizontal and vertical strings
Sounds like my shooting this weekend, only winds was 5 - 7 at the times changing direction from wsw to wnw to north. At 300 yards I saw a drop about 4" from almost one hole group from warm barrel and at 100 yards there was a jump 1.5" from cold barrel, so I limit my fliers to copper falling caused by excessive speed, basically I was shooting 55 gr bullets at 3300 fps. In your case it might not be related, it seems you have a walking barrel or scope, or even scope mount issue. Check to see if you barrel free float and you crown isn't mess up, then check bases of the scope, check torque on every screw, then check you rings, check inner surface of the rings, sometimes its good idea for rings to match surface of the scope, there are few scope bedding technics. You can also try to let someone else to shoot, see if it changes anything... Good luck.
