There is nothing you can do to the bow to improve the momentum transfer (Newton's law is about conservation of MOMENTUM, not energy).

The mode of momentum transfer is impact and friction.

So you can:

Convert to a punch cut head to get more impact, which also tends to create more local trauma along the wound channel.

Add blade length (cutting edge length) by either using MORE blades or longer blades.

Or dull your blades. I wouldn't recommend this one, but it'll do more ripping instead of cutting, which means increased friction, so it'll shed momentum faster into the deer, instead of the dirt.

I'm a punch cut shooter, with big blade diameters. My bow draws with right at 100ft.lbs. and I get around 95ft.lbs. onto the arrow. I don't care to put all of that work on my shoulder if it's just going to go into the dirt.
