Both the Accura and Optima have Bergara barrels and should shoot very well once you find the right load. They do handle differently, so I would recommend handling both of them and seeing which one fits you the best. Shouldering the 2, I really like the way the Accura feels more so than the Optima, but it really boils down to personal preference.

I'm sorry you've had so much trouble with your Encore- I have 2 CVA's and 1 Knight, and all 3 of them shoot very accurately.
