Anyone using Thor bullets in their 50 cal CVA Paramount Pro Colorado? If so, what is your bullet diameter?

I tried 2 different .500 dia Thor bullets…way too tight….had to pound the the ram rod with palm of hand to get them down barrel….left significant rifling marks on bullet. This was with a clean barrel. I confirmed the dia with calipers before putting them down the barrel. I called CVA and talked with a tech….said their bore is .499 +/- a thousand or two. I then sent an email to Thor telling them my situation with the CVA bore .499 …. found out they now make a .499 dia Thor bullet. They sent me a couple to try. I tried them….they start down the barrel good (estimate 10-15 lb force) then get very tight (have to put most of body weight on top of ram rod ~ with a clean barrel). Anyone else using the .499 dia Thor bullets? What is your experience?
