See, this is the math I've been waiting for. Thanks UV!

Hmmm. Interesting.


If .50 cal really does provide better ballistics, well hell, as much as I'm not a fan of giving the Gardners that kind of influence (potentially a whole new genre of paintball), I'd be hard pressed to not at least give it a shot. Again though, I'd be interested to know what it feels like to be hit by one. Or a dozen. Since, with less cost comes more paint-slinging.

What's the weight of a "vintage" .50 round? Just out of curiosity.

Edit:

Consider reasonable densities... Your "compromise" ball still has a higher average density than wet gravel.

Very nice. I love this site and you guys.

What better way to see through the bull the industry is trying to feed us?

My question: does anyone have equivalent data from a 9mm round? Or even a .22

This is combined with the fact that the higher density helps reduce the effects of vortex shedding as well.
i wouldn't say it's the decreased time. i believe the bigger factor is decreased cross sectional area. pi 68^2 is a lot bigger than pi 50^2.

50 cal would have a lot less surface area to be affected by crosswinds.

I may be forgetting my grade 9 math since it's been a while, but aren't you looking for piR2 instead of piD2?

yes, i was wrong.

but 34^2 is still a lot bigger than 25^2

Unless I'm missing something, there is a major factor going unconsidered here ... the effect of the size of the ball itself on energy transfer at impact. If the thing is carrying the same energy as a ball twice its size, when it hits something isn't it going to create much more force at the point of impact, leading to more damaging hits and other potential safety concerns?

EDIT: I see that harb touched on it earlier ... this seems to be completely unaccounted for in the graphs above, yes?

Yeah dude. This seems to be the magic factor we don't have. Since we have yet to physically obtain this new paint or be told the actual characteristics we are in the dark. Hopefully we will have either in the next 30 days. Because come hell or high water, I will obtain the appropriate data or the physical paint at worldcup if it is there.

yet the 3357 was allowed to shoot faster, and it had TERRIBLE range, and rarely broke on targets.

yippee!
