What draw weight do you think is acceptable for deer hunting? Is it like a compound bow and 40 pounds is sufficient?
I remember seeing some pretty plain 2 blade broadheads recommended on here. Do you know the name of them? What do you use for arrow and broadhead?
There has been many thousand whitetails killed with 45# trad bows. The proper arrow build is the key factor.
If you want to learn about arrow lethality, there is no better source than Dr Ed Ashby. Dr Ed lived and guided in Africa for many years. He also hunted while he was there and killed literally thousands of critters with bow and arrow and he recorded a huge amount of data on arrow performance. He often killed hundreds of animals PER MONTH and fed natives with the kills. The guy is probably the most experienced and knowledgeable person on the planet when it comes to arrow lethality.
He now heads the Ashby Bowhunting Foundation whose mission is to educate the hunting world on arrow lethality.
"The Ranch Fairy" (Troy Fowler) is also well known on the subject and he is also at the Ashby institute. He has many Youtube videos on the subject.

Ashby has an absolute TON of reports published.
Many of the reports are found on the Grizzlystik.com site.
Dr Ed advocates heavy arrows and high % FOC, along with heavy duty, durable single bevel boadheads.
With arrows in the 650 gr + range and FOC over 20% (closer to 30%), large African game can be ethically killed with trad bows in the low 40 pound range.
You may not be hunting Africa, but there is no such thing as "overkill" on building an arrow for even game as small as whitetail deer. Plan for eventually hitting the heaviest bone structure because if you hunt long enough, it will happen. Strive for an exit wound thru the offside shoulder because you will most likely be actually aiming for it on quartering away shots. For superior blood trails, an exit wound is priceless.
My personal set up...
55#@27" recurve shooting tapered Grizzlystik Momentum shafts. 200 grain Samurai single bevel heads. Ethics insert/outserts. 664 gr total arrow weight and 28% FOC.
Draw length will have an effect on your arrow performance. The longer your draw length, the longer your power stroke will be. Two guys shooting 50 pound bows, one guy has a 26" draw, and the tall guy has a 29" draw. The guy with the 29" draw will produce much more arrow momentum with 50# than the 26" guy. And momentum is more important to penetration than KE is. KE is not the best indicator for how well an arrow penetrates.
Check out Ed Ashby. He has some videos, podcasts and dozens of reports on real world arrow performance shooting thousands of live animals (or freshly killed animals in order to observe arrow behavior). Some of the demonstrations with single bevel on heavy bone are very enlightening. Ed Schiff also has some good videos on that ( on the Grizzlystik website).
Dr Ed is a pretty colorful guy with a long and interesting history. I find him entertaining and interesting to listen to.
The Ranch Fairy is definitely a "unique" guy. Some like him and some are annoyed by him. Forget about his personality and focus on the information.
