RE: BROADHEAD PENATRATION
What draw weight are you pulling? If its over 65lbs Id suggest going with the 6075s with a 125 grain head. As for a pass through, its all in shot placement. A true perpedicular broad side will get you that pass through. Quartering aways will to and extend, but a lot of times you hit shoulder on the back side. When you shoot, think of where the arrow will exit, not where it goes in. You will get better shot placement thinking that way.
By the way, welcome to the board.
