recommendation for self timing 9/16-32 muzzle brake

You’re positive it’s 9/16-32, not 9/16-24?
Either way I recommend a thread adapter to step up to 5/8-24, and then get the brake you like.

Everything I’m finding is for 9/16-24.... anything I did find about 9/16-32 people are saying find a new smith
They probably went 9/16-32 so the thread roots don’t get as close to the bore with the magnum pressures, and they’re still able to get a decent shoulder on the barrel. Still, though, it’s always really irksome when people go for barely-standard threads that aren’t common in that segment of industry...
If you’re not going to be going prone a lot, there’s always something like this - and if you do go prone, after spinning it on you can thread shut or weld shut the downwardish holes: http://harrellsprec.com/index.php/products/muzzle-brakes
Conveniently, with a 9/16-32 to 5/8-24 adapter, every muzzle brake becomes self-timing, because of the differential threading. Those aren’t the threads Chad uses @LongRifles Inc. but that’s the idea behind his self-timing brakes.
I found a forum post that TROS might be willing to make a 9/16-32 to 5/8-24 thread adapter: https://trosusa.com/suppressor-thread-adapters/
Finally, assuming Nate at MuzzleBrakesAndMore recovers alright from his COVID case, he might be willing to do a 1-off.
You might need to re-zero since nothing in the universe is perfectly axial or concentric and the bullet deflects slightly to center itself in the brake as much as it can (the supersonic ground effect results in a projectile deflecting slightly away from walls), but it should only be a couple clicks at the absolute worst case. More than that and you either got very unlucky with tolerance stackup
That said it’s still a good idea to double check that you have bore clearance and won’t get a baffle strike!
Side note - if you don’t have a ~0.2” diametral overlap between the outside of the barrel shoulder and the inside of the threads on the brake, you will need a shouldered adapter not a free-threading one. Otherwise there’s nothing for the threads to push against and the brake is likely to come loose and at best fly off down range.
possibly but literally anything touching the barrel could affect poi. I’ve tightened my hellfire universal adapter a little too tight once and it made my groups go to shit. But I just put it back on a little past hand right and it was fine.
So you were correct about the shoulder .... this is what my smith replied just now
“
It's 9/16x32 is what you have which isn't as common as the 5/8x24 but with the 30 cal hole and the smaller diameter barrel it was the correct choice....5/8-24 would have left little to know shoulder.
You can find 9/16x32 brakes but they aren't as plentiful.”
