Maximum FPS in the next 10 years?

Maximum FPS in the next 10 years?
hey all i was looking at excaliburs arrow trajectory charts and saw one for 400fps so it got me thinking.
is it possible for excalibur to make a 400+fps bow that can still be cock with one of the rope cockers? what would the draw weight be on one of those puppies?
i know we dont need that much speed because the bolts will probly go through targets too much but it just has me curious.
thanx for any input.

There's something already out that can launch a bolt/arrow in the 435
fps range. If you search the archives of this forum you'll find it.
Or you can just click this link.

Maybe....technology is a funny thing. As an engineer, I am somewhat involved with it everyday!!
In 10 years...who knows what kind of new materials will be invented. I am sure a revolutionary lightweight yet strong material will come along that will possibly enable a recurve-style crossbow to propel an arrow at 400 fps.
The biggest factor as you alluded to is the limitations of one's ability to physically "draw" or cock a crossbow that is capable of 400 fps. With today's materials, I would guess something in the neighborhood of 300# pull weight to get 400 fps. I don't think the average person could draw that much weight with the current string cocking devices!!
But...never say never!!

I wonder how fast the crossbows shot that were build ten years ago.
Swisscrossbows new model already shoots 370 fps!
And there is another point that I'm thinking of: The Exomax is already so hard to pull that most of the people cock it with a cocking aid. But if you use the cocking aid I think it's no problem to pull a bow that is much stronger. So if there would be a 300 ib crossbow, why should there be a problem by cocking it?
The crossbows that were build 500 years ago were also strong and nobody tried to cock them by hand.

These historic designs usually seemed to have short power strokes from the originals I have seen in various museums; so does the replica on the link.

Gary, I think that after the Max we go to siege weapons.GaryL wrote: don't know fer sure, but in my book thats about what they are doing now More or less....345fps been around fer a couple years in a compound xbow and in a recruve I think anything over 225# is over doing it for the AVERAGE person.

Tales from the grapevine might suggest that some are already beyond their limits.canadianhunter312 wrote:im very eager to see how fast companies can get crossbows to go before they call it quits on the speed and just come out with different models.
x-bows really arent that different in fps so maybe they are already at the limit for materials available today?

As an engineer myself I cant think of any "limit" so long as you put enough energy behind the bolt. Of course, a mechanical device to pull the "limbs" back would be required.canadianhunter312 wrote: excal bows really arent that different in fps so maybe they are already at the limit for materials available today?
I think the "limit" today is based on what a person can pull back manually with a simple 2:1 ratio aid. Plus, some states have poundage limits for hunting purposes.
