Warbow FPS?

Hello Everyone.  Just out of curiosity, I was wondering if anyone ever shot a warbow through a chrono and clocked the fps.  I would be curious as to what the fps would be for a minimum of 100# shooting a true war arrow, and also a more modern carbon arrow with a heavy gpi rating like 10gpi+ and something like a 300 or 250 spine.

Looking forward to the results!

Never done it... and not interested in speed. More concerned with cast. Would be interesting to know fps, however.

Thesquirrelslinger:
Big, heavy arrows do not need as much velocity to get the hitting power and KE of a normal (lighter) arrow.
KE= penetration/damage.

adb:
Big, heavy arrows do not have as much velocity, but they have more momentum. Momentum is mass X velocity. And yes, it will have more kinetic energy, which is the energy an object possesses due to its motion. I think that's what you were trying to say?

As an example... would you rather get hit in the head with a golf ball going 50 mph, or a ping pong ball going 100 mph? I'll take the ping pong ball, thank you very much. It's similar with war arrows. They're not travelling nearly as fast as a carbon fiber arrow shot from a static recurve, but they hit much harder (and penetrate more) due to their greater mass. For me (shooting war bows), I could care less what the velocity is. If I get a cast of 200 yards or better with 60+ gram livery arrows, I'm a happy camper. Knowing the velocity would be interesting, however.

There was a TV series a while back... I think it was called "The Weapons That Made Britain" and there was a program on the longbow. They did some testing on penetration and velocity, etc. It was interesting. I think if you google it on you tube, you'll find it. They did some velocity testing with a Doppler radar(?) with Mark Stretton shooting a heavy draw weight war bow.

adb:
I was re-watching the Doc on 'The Weapons That Made Britain - The Longbow' and on episode 2 they were doing some penetration testing. With Mark Stretton shooting a 150# warbow, they indicated 52 meters per second initial velocity (which is about 170 fps), but they didn't say how heavy the arrow was. I'd guess he would probably be shooting at least a 65 gram arrow, but it could be much more. That's decently impressive with a heavy arrow. That would be average for a target weight arrow, but with the increased mass of a heavy arrow, that would give it very good momentum. IMHO, the arrow head they were using for the armour penetration test was rubbish. With a proper heavy head, and a 1/4# arrow, I think the results would have been different.
