Minimum drawweight?????

[Margly]

Hi!
I know that this topic is a ever going discussion but here`s my question?

I've read a lot of the things written about minimum draw weight for  div. animals.

Lets look at whats recommended about a water buffalo:

Minimum 70lb and 800+ gr Arrows
Solid 2 Blade

I've also read that if you can pull more weight that's`s highly recommendable.

This is for me perfectly clear, but what I`m wondering about is this:

What momentum is recommended?

Example: I shoot a longbow ca 80@drawlength
800 grain arrow  170 fps

The numbers would be:
800X170/225218 = 0,60 momentum

What if I shot the same bow with a lower draw length?

Ex:
800X160/225218 = 0,57 momentum

Is that enough for shooting a Buff at normal distances etc?

Is it OK inside the recommendable zone?

Or should I at least have 0,70 momentum for being OK for this hunting?     :confused:  


Because if I cant pull 80# I might go for 70# and maybe the the calculation is starting to be pretty low??


Thoughts about this from the experienced parts of the TG family please

Are you going buff hunting?

The last buff Dr. Ashby took was shot with an arrow that only had something like .465 momentum.

Don't know for sure , but if memory serves me right it was a one shot one kill.

Definitely ask on the Dangerous Game forum. You need to talk to experienced buff hunters on this. Paper numbers dont mean much to an angry buff with an arrow in his rib!
Very exciting Ronny, cant wait to hear more!
I shot two bison with a 76# Silvertip with a near 1000 grain arrow setup, but was lucky enough to not hit bone either time.

'More than Adequate' is the answer you are looking for.

For posing a question to an audience of which >99% likely have absolutely no experience concerning the toughest game on the planet is a basis for rationalization.

Pleas conider posting this inquiry on the Dangerous Game or The Dark Continent forum. Even consider submitting this question to known highly qualified sources. Ex. Contact Dr. Ashby - a TG member who actively responds both graciously and candidly to numerous inquiries.

Ask the pros for sure!  Dr. Ashby, etc.....     Read the Ashby reports in full.   I have been doing a lot of research with the intent of hunting dangerous game.  I am working to obtain an optimized 60 lb bow of modern design and material that will shoot optimized arrows and broadheads.  My research and discussions here and with Dr. Ashby's input on the discussions have led me to the bow and arrows I am working on putting together.
