He missed by a few thousandths.

Boat tail split...

Still better than I could do.  My daughters boyfriend splits arrows pretty frequently with his bow.  Not entirely on purpose at 10 or 12 bucks a pop..

It would take me several tries to hit the arrow at all. The way the bullet pitches upward is amazing. I would expect maybe a little deflection but nothing like that. It sounds like he may give it another try.

It's amazing how easily bullets will change direction with minimal contact.

Yeah, I still can't believe that a bullet with that much mass and momentum would be deflected that far. I thought it would basically plow straight through the arrow and the backstop.

I think if the arrow had been solid there would have been less deflection.  That's carbon fiber and hollow tubes have unbelievable strength.  It's an engineering thing...though I can't remember the exact strength of materials and force vector information...too old.

Yep.

That's why drive shafts and pylons are hollow tubes.......been a long time on the math terms.
Does the second-moment-of-area thing apply??  ;D  ;D  ;D  ;D

I don't think anything hollow is stronger than something solid, but it's much stronger for it's weight. Using a driveshaft as an example, if it was solid and say 3" in diameter, it would be strong but heavy. If it was solid and weighed as much as a hollow one, maybe it would be an inch or possibly less in diameter. That would be easier to bend than a 3" hollow one. A solid carbon fiber arrow should be stronger than a hollow one of the same diameter. A solid one weighing as little as a hollow one would be too skinny and unusable.

Correct......and, I don't think anyone is saying that hollow tubes are stronger....... just more efficient, as in "strong enough to get the job done without having to spend a lot of money on excess materials if you used a solid" ..... which is exactly why drive shafts are hollow.
A hollow tube of the proper diameter, weight and wall thickness is "strong enough" to take the place of a solid tube....even if the solid is stronger at a smaller diameter, it would be heavier than the larger hollow tube. It's a balancing act of engineering.
