.68 and .50 125 Foot Flight Time Test

This is a secondary test using video collected during the .50 cal accuracy test. Using video of shooting at 125' we are able to determine flight time for the .68 and the .50 paint. Using ripped audio from the video we measured flight time - then corrected for the speed of sound to make up for the camera position.

data sheet showing uncorrected as well as speed of sound corrected information is here: http://spreadsheets.google.com/pub?key=tZnTfqfeDxJC8poRoOh1ABw&output=html

What about 250 cal o.0

[tbyte]

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

[matrix02paintball]

why such low velocity

[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.

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

[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!

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

[hellfighter22]

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

[0bligh]

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

[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.
