As to your deer dropping to the shot with a broadhead, as an experienced bowhunter myself all i can say is that you must've spine shot a helluva lot of deer. Having bowhunted myself for around 20 years, being a former PBS member & having literally all my friends be bowhunters, the only critters I've ever personally witnessed, or heard of first hand dropping at the shot, were spine shot. Most have run at minimum 30yds, the larger percentage far further, simply because that's how arrows work. There isn't the sudden blood pressure drop or deflation of the lungs like you get with a bullet. It's a slower process altogether & the 'bang flop' just doesn't happen as it does with a good bullet, from a suitable rifle. I've seen deer simply not react to being hit with a good COC broadhead & carry on feeding for 20 or 30 seconds, I've seen them tuck, buck, rear, backflip, roll & go through all sorts of acrobatics before setting off at a dead sprint, but the only time I've seen them drop, they had their spine severe or shattered & were very alive, but paralyzed.
