I zeroed at around 80 yards as thats the distance I have behind the shop with a gunrange already setup with a huge dirt backstop. Here is my 8 shot group on paper, from a bench, while trying different factory rounds and handloads.

After I got done tinkering with handloads, I wanted to see how they did at distance from a prone hunting position so I setup a target at 200 yards shooting prone off my pack to see how much practice I need to do before my elk hunt this year. (Surprise, I'm going to need to practice a ton) I was aiming for the center circle. Top right shot was a flyer I pulled.

I then setup my target at almost 300 yards (closer to 290 as thats the longest area I have without open sky behind me) and this is what I got.

Now here's the issue I cant figure out. I used the same point of aim for all 3 distances. I didn't adjust my turret or make any elevation adjustment. It actually hit HIGHER at 200 yards, and hit back at "Zero" at ~300 yards. Based on the specs on the factory ammo, I should have been 7 inches low with a 200 yard zero. The only thing that makes sense in my head is that I "zeroed" on the "rise" of the arc of the bullet path and not on the "fall" of the bullet path. (Does that even make sense?) I drew a diagram with my kids chalk to try to help myself figure it out.

Does this even make sense? I did the same exercise with factory ammo as i did with my handloads and it turned out the same both times. What is going on? How do I fix it? How am I this slow to figure this out?

Details of my setup:

Weatherby Vanguard 6.5prc 24" barrel

135gr Hammer Shock Hammer 3150fps

Also 130 Barnes Factory Ammo 2950fps

Leupold VX-5HD 3-15 x 44

I was trying to think about it like my archery setup and what would happen if I accidentally zeroed my 10 yard pin at 10 feet. Wouldnt it be higher at 20 if i used the same 10 yard pin because I was on the front edge of the arc? But now I'm confusing myself the more I think about it. Surely there is an obvious solution Im not thinking of. Right?
