Buckeeboy, I too was a little anxious about 52lbs being enough. I shoot telephone pole sized cedars and a dacron string so I was a little nervous.
Not anymore. The shaft passed through both sides of the chest cavity, just passed the fletching. The blood trail was such that a blind man could follow it. Also I used Bear Razorheads I found on some old arrows at an archery shop. It was a broadhead I could actually get sharp.
Here is another pic of the bow I thought turned out to good not to share.
