For all the bowhunting theorists out there
Ive giving a seminar this weekend on broadhead lethality/sharpening and bowhunting for the Wisconson Bowhunters Association's 80th annual convention. Im their corporate sponsor for the even and they asked me to give a talk. This is a little of the content for that talk.

using the same chart and data your 800 gr arrow beside arriving .2 seconds slower at 60 yards will also have a drop of 154" while the 450 gr arrow will only drop 91". That's over a 5 foot difference. There difference in KE is only 4 ftlbs at this distance. You will have more penetration with your heavy arrow which is definately a plus when shooting at large dangerous game but not really necessary for deer elk or black bear. In sparse cover I would have no problem with shooting a heavy arrow. But hunting in heavy cover with small shooting windows or longer distances like out west for antelope I'd much prefer the lighter faster arrow. Both have their place and sometimes a compromise needs to be taken to give the individual his or her greatest chance at success.
Good luck on your safari and stay safe.

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

"it will work on any game animal on the planet."
Yes. Thats what I hunt with my bow. IF all I hunted was small game like deer and black bear and such, I could reduce my arrow weight a bit.
BUT!
When I do hunt deer and bear and such, I know that no matter what shot angle Im presented or what bone might be blocking the vitals, I wont have to worry in the least.
I DO NOT
worry about trajectory nor arrow speed. So long as the arrow gets there before the season closes, Im good.
KE means very little to the bowhunter. He ought to focus on Momentum and the 650 grain min. bone breaching threshold because at some point a bone will block your path even if you dont wish it to.

Well I know there is no use in talking to you because you SEEM to know everything there is about bowhunting so I'll just let you do your own thing while we both continue to successfully harvest game with our choice of equipment. So good luck and stay safe.

LOL at "BS". The Ashby studies are all the validation on the 650 grain bone breaking threshold you will need. "NEED" ??? ll damn sure bet you there are a few that wished they had t when they came home empty handed if only they would have had the proper setup to get the job done. Nobody ever penetrated to deep with an arrow but many dont penetrate deep enough. As far as me knowing EVERYTHING about bowhunting. Yes. well yes I do.
And I dont see why you are getting so upset and emotional over this. Settle down. No need for this to get you so animated.
