I would personally use the Easton Axis FMJ for maximum penetration. The small diameter slippery shafts will penetrate like a much heavier arrow, and you won't give up as much trajectory. Use 125 grain heads to maximize FOC - a NAP Hellrazer would be good, as well the heavier Slick Trick, Magnus Stinger, or G5 Montec. Or even some of the heavier Muzzy Phantom heads.
