I have owned both Proof and HCA carbon barrels. Both shot the same. I wouldn't say that one is so much better than the other. Only thing i don't like about HCA is the carbon wrap is touching the break. There is no way a carbon fiber barrel is more accurate than a steel barrel. I still own two Proof barrels for some hunting rigs. And the 7 saum barrel (24" Proof) shot a 3" group at 1K on paper last month.
