Like HCM said, there's variations. I don't think it's weight dependent. Their 124gr may or may not have a mild steel jacket...the few cases I have aren't (as specifically noted by SG Ammo).
Definitely very nice, clean ammo regardless. It's almost like they polish them by hand before shipping.

Thanks to all. I'm going to pass on this stuff. I'm a regular at my range and the folks there are great. They've apparently had a tough time with shooters bringing in steel ammo and beating the piss out of the backstops in the last year. Don't want to take the chance and lose all that I've gained there.
For the OP,
As TGS mentioned, steel / bi-metal jackets not only can damage backstops and steel targets (though usually only at rifle velocities) but they can create sparks.
The problem with sparks, particularly on an indoor range is there is always a small amount of un-burnt powder which gets blown down range when you fire. The amounts are small but on a busy commercial or LE range they can build up and catch fire if exposed to sparks.

Steel jackets on bullets made for standard service pistols like the 9mm do not damage backstops any more than regular copper jacketed ammo.
They do throw sparks, and ranges can catch fire if the gun powder residue downrange isn't regularly cleaned up.

Hunh, never considered that. Learn something new every day.
Damn you folks are squared away!
I checked what I have left and the box does not say Bi Metal anywhere just FMJ. It does jump to the magnet so even if it doesnt say Bi Metal it still may be so.
