Is the 279 grains estimated? If so, you should weigh them. a 67# bow should be shooting nearly 350 grain arrows. You should have left your arrows longer if you thought they would be a problem. Use heavier points if possible, and lower your draw weight. See what they weigh first. My father has similar arrows and they weigh 360 grains at 28" with 125 grain points, and they are spined for 55# draw weight. Good luck.
