Reading some reviews on powerbelts on Cabelas and others sites, a lot of guys seem to have the powerbelts explode on them, not penetrate etc...all the reviews I read said they loaded up hot, 150 grains either powder or pellets, all the shots on deer. Seems to me that the previous comment is right about pushing them too fast might get some unpleasant results. Thats why I was trying to get some sense of the terminal ballistics on them. Going clear through all that wet, densepaper convinced me. Talked to one guy at a Gander Mountain who hunted ml last year, shot a cow at 70 yds with 295 gr pb & 100 gr pyrodex. He said the shot went through the lungs and blew out the shoulder on the opposite side. He said the exit hole was 6" around. Said he was going to the 245 gr because the 295 caused too much damage!! Of course the elkdid not take a step which is what I'm looking for.
