Most paintballs are just that -- balls. Spherical. With the piss-poor aerodynamic properties entailed therein. Could a more-aerodynamic, yet still practical, paint-load be devised -- say, for ex., one based on the Minie ball of the ACW period?

You can do a quick search. They have a round nose and a cylinder back end.

I've always thought a pill shape would be nice.
Keep the weight and materials the same. A pill shape would increase contact with the barrel and allow a smother flight with smaller drag coefficient, but would necessitate for a magazine fed system.

Biggest problem is that they are filled with jell liquid.
The other is that you gain little I think, unless you're marker had a feed system that could spin the "pill" prior to launch. Overall, I cant be done easily.

Anyone ells have a thought?

A whole lot have to do with feeding. Anything that's not round has to be designed for some asymmetry, thus, you actually have to align your pellets. Not only that, but your eye system get's all sort of troubles, since you not only have to worry that it's there, but also that's aligned.
Second, against what most think, giving spin to a liquid vessel doesn't improves stability. Try to spin a soda 2L when filled and when empty. It's not pretty.
If you deviate much from a sphere, say, like a pill, or a long bullet, the pressure on impact might well be beyond what's acceptable. The current weight (3g max), speed (300fps/91m/s) and size (.689/17.5mm +/-1%) are designed to keep a certain pressure upon impact. As it is, it might produce certain welts. Imagine if you had the same speed, the same weight, but the impact was just half the diameter. That would have four times the pressure.
And once you get into more aerodynamic forms, safe distances change a lot.
I'm not saying it can't be done, just that it would require a completely different feeding system, weight/size/speed rules, would probably invalidate all the safety equipment, rules and field measures, require completely new logistics and probably some other issues. Basically starting from scratch. Slight deviations, like the First Strike have little of these problems (safety distances is a problem, though).

But no one remembers the original, Motneel based magazine fed paintball gun, the Machofire.

It fired little football shaped paint.

Wouldn't the pressure behind the ball need to be equal to the pressure inside of the ball? If you make the ball 'football' shaped it will try to become a sphere when the valve opens?

The pressure shouldn't be enough to deform the paint'ball' THAT badly. We're talking PB guns, not potato cannons.

They had a short and long version.

Plus there was a magazine ad around 20 years ago.
