I have a Weatherby Mark V Backcountry with a #1 barrel on it. Barely any shoulder even with 1/2-28x threads that came from the factory. I'm going to try to put a Rugged Alaskan 360 Ti on it using an SS adaptor.
I don't have high hopes because the barrel is so stupidly thin, so my concession was trying a 358 cal can instead of a 30 cal can for more clearance. If it doesn't work, it doesn't work. Rifle weighs around 6.5lbs scoped, even a brake would look like a huge bulbous wart on the end of the pencil tube.
