HSM 62gr fmj (same as ss109)will go thru 1/2 steel also, its mostly what i shoot, its hotter than i figured, on there site they rate it at 3150fps and it felt hotter than that when shot. Through Mr. Uzi's chrono at the last south shoot these pulled 3300+ out of my 20" barrel so 3150 would be about right out of a 14-16" barrel.
