Which bullet of same momentum is more effective in knocking a bear down? Lead bullet or rubber bullet?
What do you think, and why?Muhammad Danish said:Which bullet of same momentum is more effective in knocking a bear down? Lead bullet or rubber bullet?
Lead bullet, because it will not compress on hitting the bear whereas rubber bullet will compress..phinds said:What do you think, and why?
I think it's a matter of the rubber bullet not only compressing but rebounding slightly whereas the lead bullet will put all of its momentum into the bear.Muhammad Danish said:Lead bullet, because it will not compress on hitting the bear whereas rubber bullet will compress..

The explanation in post #5 suggests that the sign of the result is irrelevant. It is the magnitude of the momentum transfer which matters. That explanation plays pretty fast and loose with signs, but as long as you plug speeds in where velocities are called for, it gets the magnitude of the result right.russ_watters said:Careful here guys; if this is theoretical and the mass is the same and the rubber bullet bounces, then its final momentum is negative, not positive and the momentum transfer therefore is...
Would it not be necessary to take into account the fact that the rubber bullet deforms the bears outer layers, which spring back, but the bullet drives a shock deeper into the body and there's little to no bounce-back. I realize I might not be thinking this through properly, so this is not a rhetorical question.russ_watters said:Careful here guys; if this is theoretical and the mass is the same and the rubber bullet bounces, then its final momentum is negative, not positive and the momentum transfer therefore is...
It appears that the intended result is that the lead bullet passes through the bear while the (larger, more massive, less dense, lower velocity, lower energy but same momentum) rubber bullet fails to penetrate and ultimately bounces back.phinds said:Would it not be necessary to take into account the fact that the rubber bullet deforms the bears outer layers, which spring back, but the bullet drives a shock deeper into the body and there's little to no bounce-back.

Oh, well under that assumption I don't see how there can be any question that the rubber bullet has more body impact, but that's not the assumption I would make. Bear are big damn things.jbriggs444 said:It appears that the intended result is that the lead bullet passes through the bear while the (larger, more massive, less dense, lower velocity, lower energy but same momentum) rubber bullet fails to penetrate and ultimately bounces back.
Well yes. The momentum of the projectile is not the thing that will successfully stop a charging bear.phinds said:Oh, well under that assumption I don't see how there can be any question that the rubber bullet has more body impact, but that's not the assumption I would make.

Lead bullets are typically made from a dense metal, such as lead or copper, and are designed to be fired from firearms. Rubber bullets, on the other hand, are made from a softer material, such as rubber or plastic, and are meant to be non-lethal alternatives to traditional bullets.
In terms of lethality, rubber bullets are considered to be safer than lead bullets. However, they can still cause serious injuries, especially at close range or if fired at vulnerable areas of the body.
Lead bullets can contaminate soil and water sources with toxic lead, which can harm wildlife and humans. Rubber bullets, while not as harmful to the environment, can still contribute to pollution as they are typically not biodegradable.
Lead bullets can release toxic lead particles into the air when fired, which can be inhaled by humans and animals. Ingesting lead can also lead to lead poisoning, which can cause serious health issues, especially in children.
Yes, there are alternative options such as frangible bullets, which are designed to disintegrate on impact and reduce the risk of ricochets and lead exposure. Non-lethal options, such as bean bag rounds and pepper spray rounds, are also available for use in certain situations.
