I've had 3 CVA's, and they all took a .500 Thor. The same with Jon.
I tried the FPB in all my CVA's, and couldn't get them started.

So, i'm assuming all the Bergara CVA's have a .500 bore.

I asked Hornady what the diameter of the FPB is, and they told me .503. Western Powder found out the same thing. See link below.

I'm finding it hard to believe that a .503 bullet can get down a tight bore.

Does your gun have a Bergara barrel. Not a hard question.
