Accuracy of .22 LR Stingers

I have found that the hyper velocity 22 cartridges work fine in a bolt action, but don't group well in my Remington 552.
 
In my 10/22 I really cant tell the differance but my Savage 23A I sure can. They do shoot a lot flater but the dispersion at 100yds seems to be at least twice the size as most standard HV loads.
 
Do you guys see a big difference in horizontal deviation when switching from one brand or grain of ammo? Is there a pattern to this change as far as grain difference?
