Scrub the chamber real well with a chamber brush dipped in solvent. Some steel rounds can leave sticky goo behind from the coating they use to prevent corrosion of the case. Clean your BCG and slather it in oil just before you hit the range. Too much oil is better than too little for a newish rifle. Then fire a few mags of good brass ammo through it. If the brass rounds have problems send the gun to S&W for service. If they don't you can assume it was the ammo and not the gun.

I've had steel rounds stick in the chambers of my ARs, but not as often as you describe. I've not had failures to feed with them, though. IMO Wolf is better than Tula when it comes to steel rounds, and polymer coating is better than lacquer coating as far as not leaving sticky residue in the chamber.

The failure to feed, though, makes me think the bolt could be out of spec.
