In the old days shooting aluminum arrows with the tapered nock point, it was hard to do. I did it four times and I shot alot. Lots of busted knocks and gouges in the aluminum. When I switched to carbons this year, WOW, four robinhoods in the past three months. Again, I shoot a lot. I saved the first one and pull the rest apart cause my arrows are expensive. I shoot Carbon Express Terminators and like most carbon arrows, it is basically a hollow tube and if you break a knock, the arrow will continue down the inside of the shaft.[:@]

In the old days if you wanted to cheat, you cut the tip off the taper so the next arrow shot had a place to start down the inside of the shaft. Todays carbons are already hollowed, save for the plastic nock. I now shoot my carbons, one arrow at one target.
