Ruger Hawkeye 375 Ruger barrel thread?

[KuduKiller]

So I’m looking into muzzle brakes and I know my PH will hate me. I’ve taken numerous big game animals with it but I’m tired of that recoil. I’m considering a Terminator T5 brake but which thread do I need? My barrel is not threaded and the front sight blade is sitting on the end of the barrel. I have contacted a gun smith about the threading of my barrel. The threads 7/8x20, 7/8x24 and 3/4x24 are available on the terminator. Which might be the best for my barrel?

Your PH and nearby onlookers will hate you for sure. Can't help with the thread choice. But instead of ruining the end of the barrel with a muzzle brake, have you considered a recoil reducer in the buttstock. I use them on 375 and 458 Lott. Tames it down quite a a lot. As I despise muzzle brakes
