You can put any barrel on that Ruger like Kreiger,Pac-Nor,Hart,Rock,
Lilja,Broughton,Lawton,Brux,Shilen etc.
Shilen,Kreiger,Hart,Pac-Nor offer rebarreling service not sure about the others I mention but they could rec a good gunsmith to install a barrel for you.
Most have a mim contour that they will flute and that contour more than likley won't match your factory barrel so have to open the barrel channel.
I've got a Rock 270 barrel at gunsmith now for a 270WBy only barrel I mentioned above that I don't have on a rifle is a Brux.
Well good luck.
