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.
ceolith:
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. ;)
Ian.:
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.
PatM:
The 10 grains per pound 200 fps" impossibility" is at 28" not '32"
Maybe Simon just has a way better "rolling loose" lol
