The Bone Collector is a bit pricey and the regular Triumph is just as good unless you intend to shoot loads with a great deal of recoil. With anything up to 120 gr of Blackhorn and a 300gr bullet I like the regular Triumph.
The Accura is a good gun, the best that CVA has ever come up with, so if that's what fits and feels right why that's what you need.
Shoulder the guns try the triggers get the one that's right for you, what fits and feels good is what will work best for you.
