Where are you testing? What's the layout? I've been having similar problems trying to work up loads at 200 yards. I think I know why after Friday's session now.
I was having a hell of a time at 200 getting the accuracy I expected. I was a little annoyed, so for s**ts and giggles I thought I'd throw some Hornady Factory loads to the 300 yard line and the 500 yard line, all on steel. At both, they had a set of steel plates hanging, the kind that start with a large one and progressively get to a small moa target. (I should have taken a picture! :/)
At 300 I was doing well to hit the 2nd largest target.
At 500, 3 mils up, I checked my zero on the steel silhoutte. I dialed in at .3 mils right. At this point I went straight across the steel plates, hitting dead center, some multiple times, up until I missed the last one. Now I know this rifle is a shooter.
The way this range is set up, you can shoot 100yards, 200 yds, 300 yds, & 500 yds all from one bench, all with 15"-20" mounds of dirt. It's a 100 yd mound, with open field behind it, to the far left. The 500 yard mound off sets it to the right with a thick tree line behind it. The 300 yd mound off sets it with open field behind it. And the 200 yd mount off sets it with open field behind it. There's normally a wind coming right at the bench veering off to one direction or the other.
What I suspect is happening, is that there's wind coming over the top of the mound and is extremely turbulent as it comes down the mound. I think that tree line is preventing the wind from being disruptive at the 500 yd mound.
I had been convinced it was me, with a 20% chance something wasn't installed correctly. My last session there I was talking to a shooter that had described getting unpredictable results at the 200 yd and 300 yd points on several occasions. This and my results at 500 yd mound, leads me to the above conclusion of turbulence.
I say all that to say try shooting at a different location.
