What are your bow specs? Just curious
That's also an important piece of the equation (speed x mass).
I've never been a speed chaser, but I remember when some of the "speed bows" were just getting over 250 fps and all the criticism about how you don't need that kind of speed to kill a deer, lol.
Of course, as bows became better, even the 'slower" bows benefitted from the better technology. I won a Mathews Virtex two years ago and gave it to my oldest son. It was a much better bow than my old (2005) Switchback (and much faster), but I love my old bow. It was never super fast, even at 72# @ 29". A few years ago, I lowered my DL to 28" for hunting in very cold weather with heavy clothing and a draw weight of 63#, so my arrow speed is not fast.
Last year, the buck I shot with the 562 grn. arrow with a 200 grn. Afflictor BH was standing broadside at 15 yards and just as I released he turned slightly quartering to me. The arrow disappeared. I was pretty sure I heard him crash up the other side of the thick hollow, but I waited three hours til I got down. He made it 150 yards and after inspection, I clipped his scapula, got the near side lung, liver, guts and shattered the femur bone of his far side rear leg. After skinning him at home, I found the last 8" of the arrow and fletching still in his leg but the rest of the arrow and BH had completely passed through. I went back a few days later and found that part (with no damage to the BH).
