What's your experience with Powerbelts? I was on Cabelas reading the reviews...opinions varied considerably. Some mentioned that there was poor penetration/blood trials while others had very positive comments. It seemed that a lot of the people who had penetration issues were using magnum charges??? Many of the favorable comments came from hunters using (2) instead of (3) powder pellets or medium instead of magnum charges??? It seems that more powder should equal more penetration...as long as the bullet is of sound construction???
