Can anyone tell me what the thread size is on a Browning BBR. I have a friend that wants a 300 ultra mag put on. I dont know if the barrel shank will be big enough.

I forget the exact size... but it will handle it... I made a 338-378 on a BBR with no problem... making the magazine feed will be your biggest problem...
I've been pondering the idea of a 338/300Ultra Mag on a Win 70 1.00x16tpi, just because I have a spare action and barrel blank and reamer. I was thinking I'd open threads to 1.062 (or 1.082) then I find out that Ruger chambers the WSM on the #1 with 1.00 tennon so I might just go ahead with it as it is. (Thinking about it but still not convinced.)
I wouldn't ream a bigger chamber on a inch tennon if someone paid me extra to do it.
I am trying to figure out if a browning bbr with a shank size of .937 is strong enough for a 338 Lapua. The acting looks so much like a Weatherby I was wondering if the shank size is the same. I know a Weatherby Mark V is strong enough, and I know the 9 lugs of the BBR are strong enough, but that shank looks small. I was told a Ruger No1 has a .937 shanks . Can anybody confirm that?
Is the BBR the Browning that has the pressed-in threaded barrel bushing, or was that an earlier model?
I used to do a lot of work on my own Number 1's. They are 1"x16, just like the M77. Just a different length.
As an aside, I lost all my faith in what I knew about barrel stress and sizes when I bought a new fluted takeoff 338/06 Weatherby barrel when they were moving the factory and changing some specs. I wanted to put it on a M98. I had to make a bushing because it turned out they used a tenon on these rifles something like 7/8". It amounted to having only 0.2" between the case and major diameter of the thread at the case base. It was small enough that I simply cut the threaded section off a military barrel, screwed it in with Loctite then turned it to shape, drilled and threaded it for the Weatherby barrel. I couldn't believe that they built that rifle with such a small receiver thread.
