gpp for warbow flight shot?
« on: November 28, 2013, 02:07:16 pm »
Dunno if I should post in Warbow, or arrows? But I figured more people whould see it here.
Prob no 'right answer' ...but...
I'm shooting at Windsor (in view of the castle) on Sunday, it's roving marks and a flight shoot ;D.
Not done flight before...
I'm going to make up some flight arrows for my 100# Elm warbow, (prob' 95# at a comfortable draw length)
Any offers for a reasonable arrow weight? I'm thinking about 500 - 600 gn ?

(I was going to shoot a boo backed Yew, but they don't allow boo backing for the flight shoot as it's too much of an advantage)

As light as possible, just like any other flight bow shot. I shot a bamboo flight arrow of about 300 grains with a 120 lb longbow but bamboo does have that unique ability to fit many bow weights.

Cheers Pat,
I'm barreling some 75 spine Maple shafts which shoot nicely from it.
Thanks for the info, it gives me some sort of reference.
We'll be shooting 4 arrows, so I might make 'em similar shaft but vary the point weight.
Maybe I can turn up some points with negative weight ::)
( I was going to go with boo shafts for the Boo backed Yew bow as it's 28" draw and I have some suitable 28" boo shafts, but they are no good for the warbow)

I don't think a 300 grain arrow in a 100# longbow would work very well for flight.  I would go for 6 or 7 GPP arrows, although the real way to find out is with testing.  If there are no restrictions on fletching size then I would make those as small as possible

Cheer Marc, I've finished my first one and its 661gn  :D
that sound in the right ball park, I just shot it out of one of my fast bows (BBY at 28" draw) not a representative test but it seemed to fly pretty clean over 10 yards. I'll try it from the warbow tomorrow.
Flights are about 1" x 1/4"
point of balance is about 3.6% forward of centre.... dunno how that sounds?

Drill out between nodes on the bamboo arrows and fill with helium, plug holes and proceed as normal!

Please take some photos if you can, Del!  Good luck.

If you see Her Majesty, tell her I think from the recordings of her speeches during the Blitz that she's a pretty cool character!

Would love to see some photos of the flight shoot on the grounds, though.  Might be interesting.

Yeah, I was hoping to get a pic of a load of longbow archers with the castle in the background.
There's a road through Windsor great park which will be closed for the occasion, which I think is rather cool.  :)

From my very limited flight shooting with warbows (so take this with a grain of salt), it seemed that there was a "Goldilocks" zone that flew best from my bow.  Lighter did not necessarily equate to farther distance. I've seen the same thing from others too, so I don't think it was just me.

Ask me what determines what that sweet spot is, and I'll likely shrug my shoulders :)

660 gr  looks perfect for me, warbows dont like to light arrows, too much energy lost.

I've done some testing and at 10 yards the arrow is hitting the target at 45 degrees. I think it needs a weaker spine or bigger fletchings.
One of my 'standard' 5/16 shafts with 100gn field point and V small flights straightens up nicely and hits dead straight, mind it's only about 400gn
I think I'll end up with 4 different arrows to try.

  Del, I wouldn't use any more than 400 grains, thats plenty of weight to drag a small fletching through the air. The lighter the arrow the faster it will come out of your bow period. The arrow has to be stiff enough to withstand being shot without flexing too much and has to have enough mass to overcome the drag. If it wrere me I would be shooting 300 grains with 1" fletchings about 1/4" tall. 30 or 40 grains point weight is more than enough to give you a forward center of ballance.
