Bamboo (and other) flooring - density

[JediGuy]

Hey, any flooring experts in the house…

I’ve got some extra bamboo flooring from an old project. Moved it across the country with me, just because.
When we installed this stuff a few years ago, it literally broke nails from a nail gun. This made me curious: how well would something like that stop a 223/556 bullet? 9mm? What about other types of flooring material?

My experience is totally the opposite. Maybe our contractor got crap bamboo. The stuff we had in our condo was soft AF.

Are you looking to use it as a BR material or just wondering if it will stop rounds?

Ive designed a bunch of BR teller lines for banks and lobbies but Ive never used flooring as a BR material LOL

Thanks for bringing this up from a curiosity angle. No idea on an answer to your question, but bamboo is fairly hard(as is hickory).

That is an interesting combination considering their use in traditional bow making and the norm with most materials being the harder it is the more brittle it is.

This really is just curiosity. I will probably use it somewhere in a new house, and thought of putting using it on a wall. Just stimulated the thought.

More curiosity: what did you use for teller lines?

I used it over two layers of MDF for my reloading/workbench and it has held up very well.

I'm in the Philippines right now, my in-laws live in the Jungle. No BS, the absolute Jungle.
Tallest plant in this Jungle, Bamboo. So many uses for it here, they're making everything from houses, eating utensils, scaffolding and everything under the sun.
Essentially Bamboo is a form of grass and highly invasive.
I have watched my Mother in Law weave baskets with it, I've also seen those baskets that seem rather thin to me hold 20 kilos of fruit
So it has some amazing strength.
edit to add my Wife says 25 kilos. That Baboo is strong for as think and light as it is.
