New size paintballs?

[Buddha 3]

Sure, if you apply uneven force. If you apply even force, there is no deformation.

Huh? Tell me you are joking.

An even force applied to the entire surface of a perfect sphere most certainly deforms! This is the exact principle on which the atomic bomb is based!

And as Pete pointed out, there is no even force applied here. There is an applied force on one half of an object, which can hardly be considered even. In fact, it's as lobsided as can be.

Now, as far as deformation causing spin is concerned, I am in agreement with you (shock, horror). Let's for argument's sake say that a paintball is perfectly spherical. When a force is applied all over one half of this sphere, this will cause a deformation that is predictable, rather than random. In other words, when looked at from the front (i.e. the exit end of a barrel), the ball will be symmetrical. So the face of the deformed (to whaterever extend) ball that is presented to the outside force (drag), will be suffering from equal amounts of drag all over, meaning no spin. No argument there. I never said it would.
Depending on many random factors, like how the seem on a paintball will "fall" into the breech of the gun, a slight amount of spin may occur, but not enough to do anything meaningful.

If we were to bring back the good old rifled Armson barrels however...

Smaller balls to fuss over, so hopefully less debate.

But would the proposed higher velocities used means the ball deforms more or less when accelerated?

That depends on so many other things besides size. (ooh er)

Not knowing the properties of the shell it would be hard to answer that question. If, as previously stated, the rigidity of the shell increases as the force increases, then one would expect that the answer would be neither, but as the rate of acceleration increases then the rate of deformation will also increase.

Hang on, if the rigidity of the shell increases as the force increases, what happens on contact with the human body at close range

Bigger and better "owies"

Ain't it funny how Hellfire breaks when dropped from chest height, but comes out of your gun in one piece, or sometimes just bounces off people?

To answer the question, when shot at a human from close range, if the angle at which the ball strikes the target is close to perpindicular, most of the energy stored in the ball has nowhere to go. It can't deflect. Kinda like hitting a wall. So the ball is bound to break.
However, if the ball hits at an angle, it can deflect. Or if it hits a patch of flab (fatty tissue), the flab can absorb a lot of the energy by spreading the energy out over a large area, just like a bullet proof vest does. Then the ball might not break.

So again, it depends on so many factors.

Now sorry Boss - you are generalising
We are looking here at that 10% (approx) of balls that impact in such away to cause bruising. As seasoned ballers we do not really care, but consider the first thing that you hear when you listen to a "public" conversation about paintball and the 2 words that you hear are "hurts" and "bruises".
If the change of paintball increases the severity of the bruising or % of balls that can cause bruising then we have an issue. Parents, especially in the UK, do not like seeing their kids with bruises

Smaller ball does not mean bigger brusies.

Kingman .43 cal fires at 2 joules (normal paintball guns fire at 10 joules), I have shot myself with the kingman training and there was not a brusie just a red mark which was gone in a couple of days. So if the ball size changes and they change the joule output then problem solved.

This is where I get confused. (I only got a C in physics at school). Is not a joule how much effort/energy is needed to move the object in a direction (in a straight line?).

However, in order to make them more accurate we would be firing them at a faster speed. (assumed)

Surely this would mean that a direct hit where the force is directly applied to you and not deflected or anything would hurt more?

Don't argue with Mods, especially with pseudo-rhetorical questions. It just is. Piper has spoken (typed).
