I have shot a Wolf and it was an accurate rifle. I am not sure which of them have a BERGARA BARREL. I have been reading the descriptions of the rifles CVA makes and when they discuss the Accura and Apex they point out it has a Bergara barrel. This is not the case for the Optima or the Wolf. But if the barrels are made in the same factory, then would that not make them a Bergara barrel? I think they both do, but can not swear to that fact.
I personally handled the Optima and liked the way it shouldered. I have even considered purchasing one, but have talked myself out of it. I would also go with the Stainless Steel barrel. Very easy to clean and maintain. Actually it is easy to SEE fouling compared to the blued barrel.
I am sure either would make a great hunting rifle.
