I have two Annie 54's and a Vudoo. The Annie's are single shots and now collect dust. Will one outshoot the other?, in my opinion, no! They both shoot equal at same distances with same ammo. Vudoo is a 16 inch Ace barrel in Kukri contour and a Calvin Elite Custom trigger. I do give the edge to the Annie trigger though but not by much.
I hope this helps
