It was turned back to just behind the front sight and threaded. I am sceptical because I don’t know how far back from the muzzle the barrel is “choked” for want of a better way of describing it. It has sentimental value as it was my first ever rifle when I was a kid and I sold many years ago. Was looking to get it back.
If it wasn’t for that fact I would even look at it.

Why was it shortened and did the person know how to re-crown it correctly.
Brno Model 2 Barrels are Hammer Forged, they are not .22cal at the muzzle end but actually less in a type of extruder format in that the bore is tighter at the muzzle end. How much and/or how far the taper goes I don't exactly know. I have never slug'd a bore but a .22cal mandrel for a normal .22 Bore Sighter will not fit in the end of a Brno 22 but will fit most other .22's that I have ever tried. I believe this is one reason why the Brno Model 2 is considered such an accurate rifle.
In my view 2" at 100m is just average for a good Brno Model 2 using the most accurate ammo it likes and that type of ammo has to be found like any other .22LR.
My own 1965 Brno Model 2 with Eley Match and/or Lapua Centre-X in good conditions will produce 5 shot groups at 200 Yards/Metres of 3" or less, quite a number of groups less than 2" but so far not quite as low as 1" but close a couple of times. I would call this one an excellent version of a Brno Model 2. If mine started shooting 2" groups at 100m then I would want to know what has gone wrong.
I know of two other Model 2's and a Model 2E that are almost as accurate so there must be many, many more out there. BTW, these groups are shot Benchrest using high quality equipment like a Farley Coaxial Front Rest.
Just my thoughts and something to consider.

Can't explain that one of being loose at the end, maybe it's a bit too tight further back. There's lots of different ammo, perhaps you haven't found the right one yet.

I haven't tried that. But I have put some pressure under the barrel near the front of the forend. That helped a fair bit.
I havent tried different screw tensions.
