You could still thread it 5/8-24, but wouldn't have much of a shoulder. You might run into trouble if you were trying to run a suppressor, but locktite the brake and you'll be fine.

if it is to small chop an 1 or 2 inches off and you should be good then.

I would look at one of the 9/16 threads. That will give you a .562" threaded tennon and plenty of shoulder to tighten against. There are a lot of barrels that size wearing muzzle brakes. Shop around and find a brake that you like. Most of the brake makers offer them with some version of 9/16. IIRC Vias and Hollands are 32 tpi, Ross Schuler offers a couple of different tpi options. I can't remember what Harrel's tpi is.

I would vote a second on the 9/16, fairly common on all the hunting rifles out there that are in the lighter contours, from my experience with 10 or more of these type barrels, I really like the Vias brakes out of the ones I have used.

There are some good brakes out there that clamp on without any threads as well as some thread ons that use a clamp so the shoulder and/or timing aren't issues.

You can also go custom on the break if you don't see what you want. Threads can be cut at any size/pitch.

The factory brake on a .705" 300 Weatherby Accumark barrel is 9/16-24. You should be good to go.
