A little more history. This was a good load that turned out to be inconsistent. One bench group and two positions.

I wish the shots on these targets were labeled in order fired. It looks to me like your rifle is trying to shoot two groups on each target. That's either you being inconsistent behind the gun, or something is shifting. Or maybe dragging.
I know you said your rifle was in an oryx chassis, but I had a 700 LTR that did the two group thing until I changed stocks. Put it in a bedded stock and that problem disappeared.
As to the dragging comment. I have a 700 in 300winmag that I chased my tail with off and on for years. Three barrels, three different smiths, four different stocks/chassis, 600 plus rounds of "load development" never found anything it would consistently shoot well. Not typical for a winmag. Some days it would hammer. Reload it and it would shotgun. Ended up being the firing pin assembly. Totally fixed it.
After much reading here (a few post from Chad Dixon of LRI were most helpful) and watching a pile of gunsmithing videos on YouTube about blueprinting the 700 bolt, I tore into mine and lo and behold, that was the source of all my problems. I've done it to all my 700's now and even the ones I thought shot good got better.
If your rifle has the J lock firing pin assembly in it like my LTR did, scrap it and order a pin assembly from GreTan.
