cloud vs. vortex bbmg efficiency

Unread postAuthor: cfb_rolley » Fri Jun 29, 2012 7:22 pm

So, I was wondering what the difference in air usage is between a cloud bbmg and a vortex block setup and how low of a pressure they can be regulated to in order to still work? Reason being I want to build one that will have enough onboard air supply at 175psi to run through 100 bbs or so. I know a cloud would probably waste a lot of air, but being my first bbmg a vortex might cause complications in getting it right. also, hs anyone tried different sized ammo available in Australia?

This all depends on the chamber size and barrel snugness, like for air soft bb's an experiment was performed before:

Tight bore barrel resulted and a 50fps gain over loose barrel.

Tighter barrel also results in less air leaking out of the barrel


For a vortex i would recommend a 7 inch or less chamber, 12-14 inch long barrel and 120 psi, should give about 400 fps

Agreed, a 7" x 24" inch radius chamber should do just fine :D
But really, length means nothing if you dont include diameter or volume. Same goes for velocity. A gun that shoots a lightweight projectile @ 400 fps would shoot a hevier projectile quite a bit slower.

I like this video since it clearly illustrates the obvious performance increase a vortex offers. Just ignore the rather annoying soundtrack at one point in the video :D
