BEFUDDLED ? (pics)
 

Trying to keep this as simple as I can. Here are the givens:

.204 Ruger 32 grain Hornady Vmax, zeroed at 200 yards with mounts that are closer to low(s) than medium(s) on a 10-40X50 scope. Hold on groundhog shot is about 5 inches above center mass at 300 to 300 + yards. If not a hit, close enough to make that chuck go under ground.

Received a set of Hi(s) for a present, the first I have ever owned. Let's give them a whirl. I changed my zero to 100 yards (expediency), but all of the above stayed the same, except I moved my hold up to 7 inches and the result was 2 really ugly shots at <340> yards.

Two grainy pics attached show bullet impact, good enough to see they were down the middle, but more than a foot high.

Either the change in zero or the Hi(s), or a combination of both created this. Again BEFUDDLED ! ! !

Any ideas out there, to what created this scenario---I am lost.

A target with a 5 shot group zeroed at 100 & the same zeroed at 200 would be the best way to tell ??
