522 gn @ 170 fps 0,39 momentum whats the huntable game? lets have a poll:)

[Margly]

Hi!
First I would say yes I know, this has been discussed up7down and sideways, but still here is a question:

With a speed of 170 fps
522 gn wood arrow (do not know the foc)(125 gn up front)


0,39 momentum

I know that deer is inside the comfort zone, what about other game of larger size?

Is bear OK inside my 25 yards perimeter or should I gain more weight of both bow and arrow and climb above the 0,43-0,45 momentum range.

I will of course use razorsharp two blades.

please let me know about your experiences.    

Lets vote this

Margly,

Other opinions may differ from mine.  That said, you have a good set up for basically anything in North America and beyond.  I think I remember a slug force momentum reading that indicated for deer you are totally fine as well as caribou.  Bear are not much harder to kill, especially as their boiler rooms are a bit farther back, thus not as close to the shoulder blade area.  

I think around a slug force of .4 you are in the elk zone, of course 2 blade broad head will yield a higher mecanical advantage on larger animals.  You are approaching the slug force minimum threashold for kudu and heartebeast sized animals I do believe as the slug force minimum for those is like .41 and up.  If you went to a heavier albeit slower arrow, your slug force would rise easily.  

These figures are what I think I remember however, not what I can actually put my fingers on to confirm.  I do believe you have a very lethal set up for many animals however.

Good luck,

Bob.

Maybe I'm missing something, but what bow poundage are you shooting? Without knowing the poundage, this is why I haven't voted.

I never got into the momentum "thing". I've always been interested in a GPP (grains per pound) arrow in conjunction with bow poundage.

[Friend]

Species   Minimum momentum (in slugs)
Eland (?), gemsbuck, blue wildebeest, kudu   0,4
Red hartebeest, black wildebeest, tsessebe, nyala    0,38
Impala, blesbuck, bushbuck, reedbuck   0,35
Springbuck, mountain reedbuck and all small game   0,3
Table 2: Minimum momentum required for hunting the common species in SA.


I know of two gentlemen in particular that have no issues taking approx. a dozen moose, nearly as many black bear and a grizz with this similar set-up. They use woodsmans and snuffers. Note: the grizz was taken with a woodsman.

Personally, I would desire more however it comes down to personal ethics, personal experience, personal confidence and what is legal. Note: I no little of the lower limits used to harvest bison.

Hi!
I did not mention the bows # just because I feel that is the arrow that does the killing, not how heavy the bow is to shot. ref the setups written in your posts.
The momentum for me is a very informative way to tell if I have the proper "punch" to do the job

Margly,I'm sure you would be good on black bears with that setup.There skin is fairly thin and ribs aren't much.If you stay off the shoulder blade and upper leg bone(humerus),you should have no trouble blowing through the rib cage of any black bear.

My bows in the 50# range produce those figures.If you wanted more momentum,a 610 gr arrow would put you at .43.

[Bjorn]

I have used my 50# ACS CX to take Hogs and Elk with 625 gn cedar arrows and a good 2 blade head in the boiler room.
If I were to hunt Moose or Bison a bit more would likely be a good thing.
I agree that # can be misleading, bows are not created equal.

Amen to that! My 46# Kanati chucks a heavy (12+ gpp) arrow with authority. I'd choose it over some of my heavier bows any time. Someday I'm going to chrono it...if I ever get a chronograph    :( . I know it shoots through deer faster than you can blink.

[Earl Jeff]

Put the arrow where it belongs, you have enough to kill anything.

[Cyclic-Rivers]

How much penetration do you get?  

Then I will answer whether its enough given you Follow Earl's directions.

I`m not sure, but I would like to test out this setup on a pigs carcass. If I get the possibility to such you will be the first to know  

[Bjorn]

David Peterson in his book 'Man Made of Elk' said a 650 gn arrow traveling at 155 fps was sufficient for any Elk. That is a measure...............it depends on the situation and the shooter too.
In a perfect situation a really skilled hunter can cleanly down a big animal without a lot of power. It does not take much to puncture the heart, it takes a bit more to penetrate the second lung and if it is in the guts-too bad-no amount of power will make up for a bad shot.

LOL, I was just being a smart allec (a real weisenheimer) because I had no idea what the answer is.      

Good luck on the pig hunt

shot placement and sharp broadheads with well tuned arrows that set up will take most if not all north american animals.Have seen very light bows shooting lighter arrows slower speeds than yours with short draw length take many animals down,some quite large.Good luck!

[Elk whisperer]

I like 170 with 580-600gr buts thats me

How could the draw weight make a difference?     :confused:    Whether it's 45# or 60#, the weight of the arrow and it's speed is given, that's all that is needed. Except for maybe the arrow diameter, FOC, feather size, and how well the arrow flies and the sharpness of the head.

I agree, poundage is irrelevent. A 45lb modern bow will shoot the same or faster than a 55lb selfbow.

[Jeff Strubberg]

I'd hunt just about anything walking with that setup.  Musk ox, cape buffalo, rhino and elephant I'd want more, but I would use your setup for anything right up to Alaska moose.

[Shawn Leonard]

Can be misleading I agree, but with a shaving sharp head and shots under 20 yards, that will kill anything in North America. Plenty of moose have been killed with 50# bows and a bit over 10gpp. I find things like this a bit funny, I have been shooting around 9gpp. but my arrows are doing 200fps. I would hunt anything in NA with my set-up and I am shooting 52#s. Shawn

[Thebear_78]

I know a guy who shot thru a decent griz with a setup pretty close to that.   I don't know why it wouldn't work just as well for you.
