Not to detract from your original question about a brake- but have you considered a suppressor if you're already looking to thread the barrel? It's not as significant of a recoil reduction, but it does take a good portion of recoil off, not to mention the added benefit of reducing the peak noise, which also helps for flinching. I know the cost and wait time are both considerably more than a brake, and I don't know what your state says about hunting with one, but it's another alternative. I don't have one for my personal rifles, but have shot suppressed rifles with work- it made me consider the option for my Tikka, but I haven't pulled the trigger yet- the cost is certainly a factor, as is the fact I'm impatient and the wait time would drive me nuts. The added barrel length and weight are also factors depending on your hunting style.
