Great post! I slightly disagree. You can’t double down on mass indefinitely either. There is a reason the 50 cal is no longer the king of the long shot. Several big but not too big calibers take the cake now. KE is more influenced by velocity than mass, but let’s be honest. We can’t add gun powder to our arrows. We stick to our draw length (hopefully) and literally the only thing we can really play with is mass. Whether by length, point, insert, feathers, nock, etc, we really aren’t really playing with velocity directly. Our velocity changes based on the mass and the draw length which hopefully remains constant. We aren’t really adding anything to the equation if we remain consistent. If we could add more velocity without changing mass, now that would change something. I go back to my earlier statement. Everything is a trade off. Based on the fact that likely a draw will remain constant, and if we use same bow then bow remains same (unless we change something). Then technically every change we make outside of small changes like string material and new form, only really change mass, which in turn changes velocity. Have hope though. Because of this there is a balance. And there is a most efficient setup for the user and bow. That means there is such thing as too light and conversely such thing as too heavy. Yes you can over do it. I can tie brick to my arrow but even my recurve won’t launch it but a few feet. That said I largely agree with the chart, but for the OP sure her arrow will kill animals no problem, and I’m glad it flies great. Have fun and good luck out there OP! But since she asked for thoughts and such in her post. I still think it overly heavy for the bow. To the nay sayers that say she won’t shoot outside of 20, ok, however if you want to be perfect at 20 do you only practice at 20? To be confident there I would practice longer too. IMO. I like the chart shown above but it is overly simplistic. I’m more interested in the actual data behind it. Your mileage may vary. I do appreciate this conversation though and I certainly hope it is helpful to all.

That was really my point. You can’t increase mass indefinitely, but you can play with it more than velocity which has a relatively hard upper limit. There is a sweet spot depending on what you need (long vs short range, large vs small game, etc.). 50 cal is definitely not the caliber of choice for live targets, but for armored vehicles, it may be necessary. On the flip side, a .22 LR round will not be near as effective as a .270 or .308 at 500 yards. The real debate often/usually lies between the .270 and .308 and the .22lr doesn’t even enter the discussion. There is too light and too heavy. Then there is a range that is effective, and shot placement is always going to be king. Things go wrong so having a forgiving setup cannot hurt anything. KE matters for a bullet much more.l because the goal is to transfer energy from the bullet to the animal. With arrows, KE is less important because the goal is a pass through, which means the goal is to lose less inside the animal. That’s why I focus on momentum mostly, but I am not assassin. I’m just an engineering nerd who finds the dynamics interesting. Best regards
