I did a comparison with the Defiant HFT variant (8.5gn?) against exacts and did not find much difference, they both hit the same spot out to 40y using the same aimpoints and grouped as well as each other. I didnt do any wind testing but in still air there was nothing between them.
HFT, for people with only 2 buttucks!
