I did the same thing when I tried switching from my tru-fire release that has more of a gradual jaw opening and of coursea different feel to a scott release myself. So I ended up going back to my tru-fire. I just couldn't get used to the feel of any other release. For me it was basically the feel of it I think? Anyway to make a long story short, after more practice I came to realize that the release was never part of the equation that needed to be changed for me.

So the new Scott release feels good to you but it won't group or does it just group to the right? What if you adjust your sight? Do you have any room to adjust your sight for this problem? What I am saying is, the difference in style(feel and fit) of release could be all that is throwing off your groups and nothing more..

What do you think?
