Hey just wondering if anyone here has hunted black bears with a recurve or longbow? I've been hired to dispatch some problem bears and my new boss doesn't care how they get taken care of, just that it gets done. I thought I might try with my new bow, but I'm unsure about the arrows. I thought I would use easton shafts and some 135-150grain broadheads. I am aiming for an arrow + point weight of about 700grns for a 32" arrow.
The bow I plan to use is a Bear "Grizzly" recurve. I'm drawing about 70lbs at 30.5" draw.

Any tips?

Well, that is the bow I would use. The only other one I have is a little on the light side for bears. It is either that or a rifle. And no there isn't a going rate. I'm paid the same regardless of the number of bears shot. They are also not endangered and we are well within our legal rights to deal with them. These are bears that have gotten in the habit of eating trash, and doing quite a number on fruit bearing treas and livestock. They are not poor innocent bears minding their own business. We have used bear banger flares, pepper spray, warning shots, and rubber bullets. People always piss and moan about the poor bears. They say: "Relocate them, it is inhumane to kill them" That is in fact untrue. Bears that are habituated will try to return to human populated areas, again and again, no matter where you take them. Also you can't just dump them off somewhere and expect them to be alright. Other bears kill them for being in the wrong territory. Plus habituated bears are lost when removed from their human food sources. Would you take your dog out into the bush and dump him off expecting him to feed himself and defend himself? If you would then I rest my case that you shouldn't make judgements about things that are a: none of your business, and b: something you know nothing about.

tan the fur! if you can i will buy tanned bear fur off of you. i need it with the hair on if at all possible. 

Currently the magic ratio for broadheads is 3:1. Three times longer than broad. They provide for incredible penetration and fly true. They should have no problem getting through the thick hide of a bear. Soon as we get into our new house, and I pay off a few bulk ammo purchases  , I'm getting a few dozen new arrows and I plan to tip them with these:

I was one of the three test readers she had.  She said she was really impressed that all three of us gave her the same suggestions.

I wonder who the other two were ???

Anyways, her slinging scenes got me going in praticing the rapid fire techniques.

I don't really know. But I only want what it costs me to tan, and ship it. So whatever it costs me to produce, plus the shipping is what I will want. I'll ask the grizzled old guy next door. He'll have a better idea.

However you kill it, black bear can be surprisingly tasty.
  And make sure that the animal dies quickly: pain causes an increase in lactic acid in the muscles, meaning worse meat than otherwise.  Also, it would simply be cruel.  So I'd practise some quick accurate shooting with large broadheads; get two arrows in and the bear should be pretty well finished.

If you end up with more than one bear, I'd be happy to pay for a bear hide, even if it's untanned.
