Paintball velocity

Unread postAuthor: Lockednloaded » Sat Mar 12, 2011 2:03 pm

I've finished my paintball semi, and it sure is a hard hitter at compressor pressures. I want to tune it down to the standard 280fps that's legal in real paintball games. Before actually shooting at any body, I'll definitely get it shot over a legitimate chronograph, but I want to get it pretty close before taking it to get chrono'ed. So what I'm wondering is what sort of damage does a standar paintball marker do: through one side of a can? through two sides of a cardboard box?

I'm basically looking for a paintball version of Redwolf airsoft's poor man's chrony

This test uses layers of paper box-o-truth style to check out frozen paintball penetration, with unfrozen ones for comparison:

Terrible music but the data is there.

The youtube page suggests the data can be dowloaded but the site looks trojan rich to me, have a screen cap from the video:

Seems pretty overcomplicated, but it is a tried and true method. I've figured out the minimum Pressure paintballs pop at is 65 psi, so I'll bet about 75 will get it going 300fps
