Livery Arrow record

[ceolith]

Bullshit. If Simon should shoot this 101grams (1600grain) arrow over 300yards with a 160#@32" bow, then he need a arrowspeed over 300fps. 

But THEN it will be the first selfbow on the whole planet, who shoot over 200fps with a arrowweight of 10grain per pound drawweight.

So we know, that's nonsense...

[Ian.]

You're either not really understanding the ballistic equation or have an overly high value for R, the actual weight of the projectile at a given speed only helps the distance achieved.

2009 in Stowe, Alistair Aston shoot a 1/4pounder (1749grain) 240 yards with a 155 lbs selfyew from Spencer. That's the actual EWBS 1/4er record with a yew selfbow. I know which distances you can reach with a yew bow, i hold a actual GWBS (German Warbow Society) Flight Record with 282yards. So please don't try to teach me in ballistic equation.

What you've said isn't math at all though it's just other distances.

I have just tried to type it out but the signs don't work on this editor, I will link you to the equation on another site here: http://hyperphysics.phy-astr.gsu.edu/hbase/traj.html

Go to the velocity section and you will see an object travelling at 60m/s (193fps) from an angle of 45 degrees will land 367.3469387755102 meters away from point 0.

I really don't care for your personal distance it's not all that impressive if you do the numbers higher distances are very possible. Now this doesn't include R which is resistance, 99% of that is air resistance but this can always be reduced by good conditions and arrows.

The 10 grains per pound 200 fps" impossibility" is at 28" not '32"
 Maybe Simon just has a way better "rolling loose"    lol

[ceolith]

Whatever... try it out. Try to bring a 1600grain arrow to 300yards.  Or try to bring a simple 10gpp arrow to 300yards.

Simon did, you just didn't want to believe it.

[ceolith]

...maybe yes. maybe no. there is no offical list to see that. only a arrow...

And if he does that, than not with a self-yew.

I know that simon shoot a hickory-backed oregon yew from chris boyton for a long time. glued with a reflex in the bow these distance could be possible. but never ever with a 1600 grain arrow on a 160# self-yew

[Badger]

      That record does seem quite impossible at 10 grains per pound. For comparison a modern recurve bow shooting 9 grains per pound reached a distance of about 330 yards and is considered one of the strongest records held. I hold a 10 grain per pound record with a backed bow at 230 yards and another with a self bow at 221 yards.

THANK you for your support!

I do not recall that Simon's bow had any reflex glued in as I followed the build along in The Glade.  It was constructed from joined billets backed with and a few growth rings of hickory.  In terms of performance it should have performed the same as a self bow - unless you count exploding at full draw because the sapwood was not in a good enough condition. 
Either way, I'm not sure what you mean by 'official'.  You have a distance, you have a bow type/draw weight and you have an arrow.  You either accept it was shot or not.  Perhaps you mean it was not done under the auspices of the EWBS or GWBS.
Incidentally, the laminated heavy longbow EWBS records are no further than the selfbows.

[never ever with a 1600 gram arrow out of a 160 lb self yew] thats stierscheiss you want to find yourself some decent yew

[ceolith]

ok, you are right and i have no idea about yew and bows. 

[Badger]

From a purely mathematical standpoint a shot of 340 yards with a 1600 grain arrow would require about 164 ft #'s of kinetic energy. It is unlikely that any long bow will exceed 70% efficiency. If the bow was storing about 170# of energy @70% this would leave him with about 119# of energy. This would give him about 183 ft per second which is outstanding, almost too good to be true for this design. 183 fps should give an archer no more than about 240 yards. Anything over 200 yards I would consider a good shot.

That would depend somewhat on the ballistic coefficient of the projectile Steve.  Heavy projectiles tend to fight drag much better than light projectiles
