I don't know a whole lot about CVA guns, but the ones with the Bergara barrel are very popular because that is an excellent barrel. And with the right load and bullet the biggest problem with 200 yds is knowing the drop and the distance. I also know my 50 calibers will do it for me with a very heavy load of Blackhorn and any of these bullets.
The 200gr Shock Wave the 200gr Lehigh [under 3 inches at 200 yds] I suspect that the 200gr XTP will also but I have not tried it these are 50/40 bullets, in the 45 caliber I use the 250 gr FTX for long range, I have taken Black bear and deer at 188 [by laser range finder] but have never needed to take game any farther than that but I shoot up to 250 on gong and knock down targets. The biggest problem with long range is time of flight of the bullet an animal can be standing still when you shoot and jump or take a step by the time the bullet gets there, thats why I prefer the lighter aerodynamic bullets and heavy loads.
