Thats why they say, Use the bigger bullet. 348g minimum for elk.

You see the guy that shot the 225lb pig with the 348g powerbelt and 100g pellets @ 30 yards on modernmuzzleloader forum? he said it dropped like a sack of flour and the bullet mushroomed like one of my 295g powerbelts with 90g pyrodex select.

The bullet also hit it in the shoulder.
