learned something today

Post by GonHuntin » Thu Sep 18, 2003 4:59 pm

My new chronograph arrived today and you know the first thing across it was a bolt out of my carved limb exocet......20" 2117 with a 130 grain wasp broadhead and 5" feathers went 269.......a 20" 2117 with a 130 grain wasp and 5" vanes went 259..........

I figured the vanes would be faster????

Feathers are lighter than vanes :D

gonhuntin',

feathers are lighter, therefore initially faster.

they also produce more drag, therefore are slower downrange.

Interesting.... I have the same set-up[130 grain Wasps, 2117 bolts, Exocet carved limbs] and my bolts, with vanes are moving at 284-286 feet per second. I wonder why the difference. Anyone have any ideas?

Chris,

With carved tips you are doing very well at those speeds with that setup.
I would have expected the results gonhuntin' posted. My son shoots 165# Magtip Exocet, FFF string, 2216 (same as 2117) and 100 grain tips. He's getting about the same speed you are.

The differences could be attributed to, IMO:

A.) strings - standard dacron or flemish dacron
B.) individual differences in limbs
C.) accuracy of chronographs

Sorry, my mistake. The limbs are not carved, they have the molded mag-tips. But the rest is still true. 1000 apologies.

You may have the longer railed 175 lb. version.

vanes heavier than feathers....OK....but not much right??? WRONG.....I took a 5" feather and a 5" vane and weighed them on my powder scale

feather 3.5 grains

vane 13.0 grains

Hard to believe using vanes instead of feathers adds almost 30 grains of weight to a bolt!!!

Exocet FPS

My friend just picked up a new Exocet today and taking my suggestion, bought the Gold Tip carbon shafts with plastic vanes that Excalibur supplies in their standard accessory package. With a 100 gr. target point, he chronied 301fps. I shoot exactly the same arrows/points in my new Exomag and chronied 320fps. Hope this helps.
