You got the wrong picture

I' m shooting 2216 aluminum @ 60#
She is shooting a carbon @ 43#

I thought the KE would be equal.

I shot her carbons after I typed the start of the thread, and my bow blows them through the McKenzie pretty good too.

I thought the McKenzies had more stopping power and were a little tuffer then that? I' m messing up the unshot side because the arrows blow threw it at 30 yards. It blows chuncks out of the backside. Like a bullet would.[:@]
It won' t take long for me to need a new mid section, and I have only had the McKenzie a week, tomorrow.
