Setup a new makenzie shot blocker the other day and began shooting some carbons. Being a new target with no worn areas I notice something interesting. The footed carbons penetrated a little deeper than the non-footed. The footed bareshaft penetrated the deepest. These are ICS bemans, all have 100 brass inserts. You would think with the larger surface area and "fatter" field point the footed carbons would have less penetration. Must be the addtional 8-10 grains ? An Interesting observation but I still can't get out of the 240's.
