Got a few questions after shooting today that I can't figure out why.
First off I'm shooting a Howa 1500 barreled action in 7mm R.E.M. Mag. Shooting 150grn. Winchester power points. (Was just shooting this factory ammo up fire forming brass) I put a new leupold VX 3 2.5-10x50 on it today.
I bore sighted the gun at 40 yards then backed up to 100 and sighted it in for an inch and a half high. (Zero 200) backed up to 200, shot a 5 shot group of roughly 2 inches. Center of the grouping being 8 inches high. Went back to 100 and zeroed at that yardage. Back to 200 and now I'm still 6-7 inches high. No to very little wind, shooting downhill about 6-8'.
I'm at a loss why it's doing this. In years past with other rifles (and hand loads) I own when shot at 100 yards an inch and a half high it's zeroed at 200. At 300 it's about 3.5 low. Is it the elevation change causing me to shoot higher. To me it seems it breaking the laws of gravity.
Also had a buddy shooting his 30-06 and he had the same exact results that I did. Does shooting down or up hill that little make that big of a difference?
