I have the bravo. I like that the backbone on the bravo runs all the way down the length of the action/forend area. When I put a bipod on it, the only flex is in the bipod itself. Looking at the HCR/Accurate-Mag chassis.... I don’t trust the forend portion. That’s just me. Also, not a big fan of the luth-ar stock.
With all that said, go with which ever one speaks to you the most. You’re the one that’s got to shoot it.
