.68 and .50 125 Foot Flight Time Test

[AAVince2513]

What about 250 cal o.0

[matrix02paintball]

why such low velocity

[tbyte]

@matrix02paintball lighter balls (or anything) loose kinetic energy thus speed quicker.

[Ubernator44]

seems to me that the .50 cal looses alot more momentum than the .68, which if both where chrono'd to 300fps would make sense. by mean velocity, basicaly its takning the beginning velocity and the end velocity and finding the avg, correct me if im wrong punkworks. anway, they seem to have just timed the shot then calculated how fast it was going at the end, very simple to do with physics. wind resistance is a pain though in terms of calculation.

[Zkewlz]

if im not mistaken mass is what enables the paint to stay in the air as long as it does and maintain speed, less mass=shorter distance & slower flight so .68 > .50 in this category

[hellfighter22]

They should be fired at 350 fps.

[0bligh]

@hellfighter22  Why?

[hellfighter22]

Because its faster and it performs better, breaks more consistently, shoots further, less reaction time for the opponent, and still hurts less. That just my opinion, thats how I would use it. But then again I am just a troll who has never used a 50 cal. just talked about it with some buddies who use it.

[0bligh]

@hellfighter22 Masks are only rated to something like 360 FPS. It would be way too dangerous.

[hellfighter22]

Thats 360 FPS for a .68 paintball, they are rated for airsoft too and they shoot faster then 360 fps.

[0bligh]

@hellfighter22 I guess that makes sense but we don't know what it would be fore .50 cal.

[hellfighter22]

yes we do, just find out how many joules you get from a .68 cal at 300 fps. Then calculate how many FPS you need to reach the same joules for the weight of a 50 cal. Then BAM! you have all the free ice cream you want!

[0bligh]

@hellfighter22 But first you have to do that. We don't know if 300 fps is too fast or if we could go faster.

[slysix]

Heh...you guys really should try this with the First strike rounds.

The thing that slows down the paint is air friction against the cross section of paint. What keeps it going is the mass.

Unfortunately, the .50 looses a lot more mass then compared to the cross section. So it looses speed faster.

For the .50 to have almost the same ballistic properties as a .68, it has to weigh in around 1.7 grams not 1.2.

[brycelarson]

20 feet per second mean difference - that means a far greater than 20 fps difference at the end of the flight.

[woodsballer1994]

but which most accurate?

[MurKdAMAsK3]

uh...why yu guys shooting so slow?

[vijil]

They're not, the paint slows down a lot once it leaves the barrel. They shoot at 300, but the average velocity ends up being much lower.

[brycelarson]

average speed at the muzzle was 290

[MurKdAMAsK3]

you sir are too smart to be commenting on videos

and my question was why are they shooting so slow?

which was answered twice respectfully and you happened to reply but this time without an answer and tagged on a little smart ass comment at the end so once again i dub thee:genius

[nopopallowed]

should have been obvious no? More mass=more momentum

[Dramen20]

maybe. but then you also must think more surface area= more drag.
