Whaddya want? Soft steel jacket coated with stuff that doesn't tear up steel targets?

Ok, give the the slap in the back of the head award. ;D I didn't even think about shooting steel targets with bi-metal ammo. I'm not used to ringing steel. Until now I have been punching paper, making pop cans dance, exploding clay pigeons and blasting self sealing polymer targets.
