Draw weight can be misleading.
I have 50+ pound bows that are barely suited for rabits, and 40# bows that I would not hesitate to hunt with.
Guaranteed the 40# ACS/CX will outperform the 50# selfbow with any arrow weight. This gives us a wide range of performance to consider, not just bow weight.
A dog of a bow is a dog, but we don't need a race horse either.
We all know to have politicaly correct arrows and flight, but it realy boils down to knowing your limits with the equipment you hunt with, and not taking Hail Marry shots in desperation.
Bow hunting is about getting close, not shooting far.
I had a friend shoot a very large moose with a test bow from Rodney Wright, he drew it 39# at his 27" draw. 1 Arrow and the moose went down, and there was enough energy to bend up the broadhead on the far shoulder. More power would have just bent the head more. He picked his shot and the distance he was confident with after turning down many marginal oportunities. That is good hunting.
To much draw weight for many is giving them false security. We often see short drawing a bow that is to heavy. You do not gain anything when you can not come to full draw! Some guys are short drawing up to 3", but brag they have a heavy bow.
One guy was trying my carbon arrows and insisted he had a 27+" draw length. The arrows were marked for testing in 1" increments and he was actualy only drawing 24". When he tried a lighter weight bow I had with me he was drawing nearly 28" and shot much better. 55# was far to much for him , and a 40# at full draw was shooting the same arrow visibly faster.
Point is draw weight is not the wholy grail of what to use. Shoot what you can draw and hold and don't shoot beyond your means.
Less can also be more.
Pat has a Pecos River longbow that was to heavy for her. When we shaved it down a few pounds the draw length she pulled increased and the arrow speed actualy went up with the same arrows. Why? She ended up holding the same draw weight only at a longer power stroke, and it gave her more performance. Less can be more if you are a short draw shooter.
If we run the jackson calculators
www.bowjackson.com and use the KE / MOM values out to 30 yards we can make some informed decisions on what is good at what ranges. {They show them out to 100 yards}The arrow drop is there also, but this is something that falls under our shooting ability with that set-up, not just drop numbers.
Like I said earlier, I have bows over 50# I would not hunt anything bigger than a rabbit with. Look at the bows performance the way you have it set up, then decide . Most modern 40# bows do just fine when we do it right.
Take only high percentage shots no matter what bow you shoot, and stay within your personal limit of ability. It is better to pass up a shot than to be asking for help to track a poorly hit deer.
