Not to mention that an arrow, as a projectile, is long AF. Just because the entry is in the boiler room doesn’t mean it stayed on that trajectory or that the exit hole is still boiler. The exit, on a full shaft shot or pass-through, is minimum 26” from entry (based on my arrow length, lots of y’all are probably way taller and shoot 29-32” arrows) and if it hits anything hard on the way or the deer starts running before it’s done cutting, that trajectory can shift angles within the animal and come out somewhere you never would have thought. This is why I like a shallow quartering away if I can get it, because I can plan for the arrow to either pass through all the good stuff or get lodged into that front shoulder and keep cutting all the good stuff as it runs. That’s what happened with my doe this October. I didn’t find the broken arrow until 40yds (she died at 70) but when I watched the video back, she clearly took the thing with her and must have hit a tree to break it. Then when I gutted her, we found an exit hole but never the rest of my arrow. So who knows what actually happened in the middle of her chest? I guessed that the arrow was sticking out of both sides and the broadhead end dangled out when it broke. Speculation at best, but she died like a MF thankfully lol. Very Shakespearean at the pile-up site, blood in a 20yd radius like she was on her final monologue.Maybe because the margin of error is much greater than most archers skills at shot selection and that aiming point is very seldom where the arrow ends up because deer almost always move to some degree before the arrow gets to the intended target.
