I had to laugh when I read this - maybe the outfitter is selling arrows !!! I would like to try it though - would someone loan me their arrows. I would not put much stock into shooting a metal drum. With the min. draw weights required and using a good SHARP broadhead you will not have any problems. I have shot lots of elk with various BH's and at least 90% time have had complete pass throughs. When I did not, I usually hit the off side shoulder, never the less the animal never went more that 100 yds. I shoot a 70# recurve with carbons and good heads and have killed caribou, moose, grizzley, mt. lion, elk, deer, etc. LARGE African game might require something different, but this set up will work for all North American game.
My opinion
