The amount of drop does not equate to loss of engery. Matter of fact just the opposite. the heavier arrow will have more momentum at 30 yards than a ligher arrow. More Momentum is a good thing. More momemtum means the arrow will impact the target more aggressively than a lighter arrow with less momentum. When hunting an aggressive impact is a good thing.

Just learn to shoot what ya got. Learn to judge yardage and your on your way to being a complete hunter.

Websites are full of people trying to take short cuts buying faster and flatter so they don't have to jude yardage.
I suppose if they could go out and buy, aim, they would.
(My humble Opion)
Seems everyone thinks they can go out and buy equipment that will elimate the need to work at the fundematals of bow hunting. Well not true. slow heavy arrows were killing white tail deer for many years before there was even a fast light rig on the planet.
Guess what your 477( which is not really heavy by the way) grain arrow shot from your bow will kill a deer just fine. All you have to learn to do, is tune the bow and arrow combination, learn to hit what you are aiming at up to your maximum range (which only you can know.) then after you have learned, all you have to do is put the arrow where it is suppose to go when the time comes.
Some of us have worked many years to accomplish this.

good luck.
