SST's do what they are designed for! You have to match rifle with bullets as previously mentioned, shot them under 3000 muzzle and they are great on deer sized game. When going bigger and faster do same with bullet construction. I got a pile of racks in the garage that will speak to fact they work on whitetails but I will say the bullets frag but work perfect on lung shots so again bullet placement prevents any blood shot. Out of a 300 shot a inter bond, accubond or partition or a mono, just my 2¢
