I would not assume that.
Why not SJ?? I thought being sleeved with modern steel sleeves would make it steel shot compatible. Would you mind explaining your answer? Merely curious. Also, have never owned or even seen for that matter a sleeved gun. Thanks.

It really depends on what kind of steel was used for the sleeving tubes. After that, it comes down to wall thickness. If the sleeved tubes were struck in a way to get the barrels weight or gun to balance at a certain point, wall thickness certainly will come into consideration. The next consideration would be how the new sleeved barrels are bored. Hopefully everything was cut/machined correctly. Bore diameter within specs, chamber and forcing cones etc. Barrel interiors cut with dimensions out of spec for the gauge can cause serious issues.
If the steel used for the sleeved barrels is fairly modern and of good ordnance quality, everything was machined correctly, wall thickness are good (which 99% of the time on newly sleeved barrels the wall thickness’s are more then adequate), chokes are appropriate…..then there shouldn’t be any issues at all with using steel or modern non-tox.
