Heavy draw bows

[Will_m]

This is not a thread for everyone to profess their knowledge on human anatomy and kinesiology, so let's avoid the "(insert draw weight number here) will destroy your shoulders/cause bone spurs" arguments and focus on the pertinent issue at hand.

Does anyone shoot heavy draw bows, as in 80+ pounds? If you do, what is the make? Seems like very few manufacturers offer them, and my pet brand, Matthews, has the Safari at laughable price. I know hoyt makes several 70-80 pounders, but are there any others?

I have a hoyt maxxis 35 and a hoyt Faktor turbo both with 80lb limbs. They both push a 560 grain total arrow weight fairly well.

Seems like every bow I've ever looked at had 80lbs as an option. I was going to get my Freak at 80lbs, but at 32 1/2" draw that really limits available arrow options for correct spine.

5, I would think with that kind of draw length and a bow weight of 80 lbs, you could shoot down low flying aircraft with the proper arrow. Have you thought about toying with point weight in order to address your spine issue?

Right now I'm shooting the Kinetic 200's which spine really well at 70lbs and my draw length. I tried the BE Rampage 250's and the 200's are a better spine. Not much you can do with tip weight to address spine issues on the high end of the spectrum. That would also lower FOC which isn't in my best interest either. 70lbs works just fine. But I must admit that if I found a bow I liked that had 65-75lb limbs I'd be all over them.

these baby's come in 150 spine... you could shoot 32 inches and 125 up front and not be too weak. I shoot the 250's with 80 lb limbs and 100 up front with a 31 inch dl with zero spine issues. Absolutely love these arrows.

Ya, was talking to Jerry at SSAS when they were designing those 150's. That's a little too much, unless of course I'm heading to Africa. Then they are a no-brainer. My 250's shoot really well out of my Old Glory, but the Kinetics shoot better out of the Freak. I cut all my arrows to 30" carbon to carbon.

Elite, pse, obsession and bow tech all make 80's.

I've built a couple of Obsessions @ 80 lbs.

none of the new Bowtechs come in 80 lbs... and hoyt quit making there "turbo" lines in 80 lbs... you would think Cam would have that fixed. That nitrum turbo in 80 lbs with a 31 inch dl would be a KILLER set up.

Can't do it, from what Hoyt told me the cams were not designed to take that much energy. Wouldn't even let me get one out of the custom shop.

We chronoed Cam's 80# Nitrum 34 against his 70# Turbo. With his FMJ Inj 330s @ 455 grains there was less than 5 fps difference between the two bows.

Got to love the turbo cam

School a nube on this please. What do you gain in terms of effectiveness for a heavy bow? Is it just faster and more energy down range?

I am very new to archery so really don't know. I have a Hoyt carbon spider turbo set at #60 on a 31 inch draw. Arrows are whatever the guys in the shop cut for me. Again I am very new to this, but from what I gather I feel like I have something pretty close to the 300 win mag of bow hunting - ie more than enough lethality for anything in North America and probably too much for a lot. Is a 338 win mag more gun? Yes. Does it really add a lot to performance? I am not sure. I am strong and could pull more, once I develop a bit better control but honestly don't know what I would gain.

Best thing I can tell you is to set your 60lb bow at 50lbs and shoot it, and you'll see the difference for yourself. 10lbs doesn't sound like much, but just shooting the bow will show you the differences. At 31" draw you already possess some of those performance gains over shorter draw length shooters.

At 70lbs and 32+ draw length, that's the equivalence to a 28" draw shooter shooting the same bow but in a 90lb configuration from an energy standpoint.

Look at it this way, and this will keep the whole speed freak aspect out of it: with a heavier bow you can push a heavier arrow at the same efficiency you could push a lighter arrow with a lighter bow. Kinetic energy and momentum will determine penetration and bone busting ability. At the end of the day, the heaviest arrow will achieve the greatest penetration, assuming it can be pushed at a reasonable speed. The only way to achieve this is more power. That's really simple and probably over generalized but it should give you the overview of some of the merits of a heavy draw bow.

As for the draw length issue, 5milesback hit it on the head, more or less.
