I don’t know which model you have, but on their site, it says the Tactical version has a threaded muzzle, and they recommend a Sako muzzle brake. My Blaser Tactical 2 had a Sako (also was .300WinMag) and the way the gun was designed it had virtually no felt recoil compared to say, a .308. On the Lite models, no magnum calibers have threaded muzzles.
Also, I have 220rds of high quality .300 WinMag here I’d love to get rid of lol.
