When zeroed at 100 yards, my Hornet shoots considerably to the right at 150 yards (3" or so). I'm guessing there's a problem with the axis of the scope versus the axis of the bore. I'm using Burris adapters with Weaver style rings in place of the Ruger rings, but those Burris adapters don't allow for hardly any lateral play. Anyone have an idea other trading it.

If you're using Weaver style rings, try the Burris Signature Zee rings with the offset insert kit. The polymer inserts will let you align the scope to the barrel without bending or stressing the scope tube.
I seriously doubt it is a scope-barrel alignment problem, as the scope would have to be off the centerline of bore by six inches to cause three inches of error between 100 and 150 yards.
If the scope was offset 1 inch at the rifle, it would cause .5 inch of error at 150 yards, zeroed at 100.
Was it windy ?

IF it is truly zeroed @ 100 yards, the horizontal impact will not be changed by that difference in distance. If it's off just a wee bit @ 100 yards,THEN it will be off more @ 150 but I doubt 3".
Look at wind as it doesn't take much to move that Hornet bullet 3" from 100 to 150.

Now that I think about it. That much deviation couldn't be from misalignment. I dug out my sight in target. It shows an 1 1/4" group centered on the bullseye. There wasn't any wind when I shot at 150 yds. I'm giving this puppy one more try before I trade it or wrap it around a tree.
Before wrapping it around a tree, I would set up targets at:
25, 50, 75, 100, 125, 150, 175, and 200 yards. Paper targets labeled with distance (for later reference). Shoot group per target, make sure no wind is present. Evaluate.
Possibles are many. Including scope, base, rings, ammo, environmental/wind, different parts of the rifle, and not forgetting the shooter.
I have used the every 25 yards targets and learned much about my firearms, loads/ammo, and my own shooting technique.

Parralax problem????
My Ruger 77/22H has a straight stock, and scope center is well short of a good cheek weld. I'd experiment with your cheek weld vs scope center next trip to the range.

Zero Problem
That is why I use Millet angle loc rings that way you use up the adjustment in the rings not the scope. I have never had a scope come loose or move with these rings as far as I am concerned only rings out there in fact only rings I use.

Thanks for all the good advice. I'm going to forego the tree bashing & give it one more chance. I ordered new brass. I unmounted the scope & am carefully remounting it. I'm also going to check the takedown screws. After I zero at 100, I'm immediately going to shoot a group at 150.
