Yes, same as in the leverrevolution ammo. Rumor is the lead is harder than the SST/SW and they may not expand as well but I'm trying them for a year to test in real life. I use the orange MMP sabot ordered online. Groups well at 135gr777, have shot out to 500yds with good groups.

I'm not as worried about expansion as much with a .458" 325gr bullet as I am with a 200gr .40 bullet. That's a big, wide bullet making a hole. Informed opinion to come in a couple months.
