Heres a test question. What has better penatration, carbon or alum? I have always thought that carbon gives you better speed and flatter trajectory but in the end you lose some penatration. The arrow just doesnt retain the kinectic energy like a heavier mass alum arrow would. And to be honest, I have personaly noticed the difference after I switched to carbon. I got better trajectory, but have had issues with blow throughs on deer and have considered going back to my old standby...2317"s with 100 grain brdhead.( I shoot a 38" arrow...596grns finished with this setup). Those telephone poles gapped my pins aliitle more but blew though a deer like a knife through butter.... Here is when I got confuzed. Just read Bowhunting Q&A in the recent NAHC mag, in there a dude is asking about using carbon for bear. I'm sitting on the throne thinking that I would want to use alum, and a cut on impact 125 grain broadhead to get the most penatration on those thick buggers. Well the "expert" agrees with my philosiphy up to the arrow. He recommends USING a carbon arrow for MORE penatration. What gives? I figure there is alot of experience within these walls of this site, so I ask you guys to give me the truth. Whats the answer? P.S. I know I cant spell.
