Is the 9mm steel shell case considered a "Steel Jacked Shell" I bought 150 of them and evidently cannot use them at the indoor range lanes.

You're good to shoot those. Steel cartridges cases are cheaper than brass. Steel jacketed or Steel core bullets damage backstops. Two different components.

They still may not let you use them unless you bring a magnetic sweep and pick up your own "brass". Ask!

Thank You. Iappreciate the info.

All to often, steel cased ammo has bimetallic bullets.
The bullets turn out to be lead-cored, but steel jacketed, with a very thin copper coating over the steel. So, the term bimetal refers only to the jacket and not the bullet as a whole.
That often causes sparking on certain backstops.
So, if a magnet isn't attracted to the bullet but only the case, you should be good to go.

Steel case is just that....a steel case. It's what the bullet sits in.

Steel jacket is what's covering the outside of the bullet.

Many companies make steel case. Even Hornady. Doesn't mean that the bullet has a steel jacket

Good advice. Ranges that recycle / sell brass, probably don't want it contaminate with steel shells.
