Using the Real tree KE and momentum calculator; (https://www.realtree.com/kinetic-ene...tum-calculator)
My set up:

Your Setup is Suitable for...

This is a stout setup suitable for big game like elk and moose, but just fine for whitetails if you can handle it!

Arrow Weight: 420 grains / Arrow Speed: 300 fps

Kinetic Energy: 83.92 foot-pounds

Momentum: 0.559 slugs

Your set up: (I had to drop you down to 750 gr because that's all the calculator would take so I increased the velocity)

Your Setup is Suitable for...

This rig throws heavy arrows, and with a strong fixed-blade broadhead, it will work on any game animal on the planet.

Arrow Weight: 750 grains / Arrow Speed: 215 fps

Kinetic Energy: 76.97 foot-pounds

Momentum: 0.716 slugs

Other than being slow by today's standards and having a rainbow trajectory there is nothing wrong with your set up. But quite frankly it is more than needed for all but the most dangerous and largest animals.
