Some of you guys know CVA barrels better than I do (considering I don't, nor will I own one) but I got my best results out of my TC barrel with those Barnes bullets by using Crushed Rib sabots. In all actuality, I seem to get the peak performance with every bullet except one with them. The TC Cheap shot bullet actually shoots pretty dang good using the supplied sabot that came with them. I don't know if CVA runs "tight" like TC's do but if you happen to have a little tighter bore then those Crushed Ribs will really help.

As far as Bronko's statement goes about compressing charges, he didn't mean just seating the bullet tight. I have found in my testing that BH209 really likes it when you lay on the ram rod. Really put the weight to it. And do your best to come up with a method that is repeatable. I "rock" onto mine the same way giving it about 80 pounds of seating pressure. My rods are marked to the depth for each load that the barrel likes. I.E. The 220gr .458 Lehigh Controlled Fracturing bullet likes a Crushed rib sabot on top of 110gr (volume) BH209 for just over an inch at 150 yards 5 shot groups.
