I used a 300 gr Thor and 120 of Blackhorn 209 for my Colorado elk this year. The shot was 140 yards quartering away. The bull ran about 40 yards and died quickly. I found the bullet behind the skin on the opposite side. The bullet has very minimal mushrooming
Not related to Thor but my friend was using 350 gr Federal Bor Lok and we called a bull in to 50 yds. He squeezed the trigger and we heard a funny sounding shot go off. Then the bull just walked off. He unscrewed the breech plug and all the powder was burned and the bullet was gone. My guess is the rubber gasket on his bullet did not seal correctly and most of the gases escaped around the bullet. Those bullets are super easy to load in our CVAs (thumb pressure). It was very strange and cost us nice 5x5.
