Tahquamenon,I was shocked when I found out that I had been dropping deer on the spot I hit them for years with my 54 at ranges that it had less than 800 foot pounds; after I thought it out I decieded that the amount of enegry involved was less critical than the way it is applied. The way a 54 cal round ball can flatten out and then roll it self back into a ball and keep penatrating has amazed me ever since I realized what was happening for a long time I did not think I would ever see an inline that had the killing power of a 54.
