I used three White Hots behind a 300gr Hornady SST ML to kill a big New Mexico Bull elk. I get consistent MOA groups at 100 and 200 yards with this load. The bull came in to 63 yards and I shot him in the neck. He went straight down. I recovered the bullet just beneath the hide in back of the neck. It weighs 248gr so it retained about 83% of its weight. At the range I shoot 3-4 times before cleaning and I am sure I could shoot more with no problem. I do not have experience with any other propellent but this is my experience with White Hots.
