What is the most common thread for muzzle brakes on different calibres?

I know 1/2-28 is the common one for AR.

What would I use on say a .308 and a .300WM? I have read everything from 5/8 - 3/4. Figured I would ask here before I went crazy reading every article on the internet!!!

Thread size isn't important...that depends on the barrel diameter and the bore... it is how accurately the barrel is threaded and the brake fitted that is important.

I am referring to precision bolt action rifles.

This is a lightweight .300 short mag with a brake I installed... it works very well and would on a .300 Win Mag also.

I would use the largest diameter that would work with the muzzle and the brake.

Thanks. That is kinda what I was looking for. I just don't want to go to thin. I will probably try 11/16 or 3/4 then for the .300. I think the Hollands are 3/4, so if I don't like the one I make I can always put one of theirs on without having to rethread.
