My understanding is that the dimples do not create the lift in themselves, but purposely induce turbulence. That turbulence is required to generate magnus force. This is why baseballs have seems, golfballs have dimples, etc.
Even for the hopup kits on airsoft, metal and plastic BBs have similar seams to paintballs, though much smaller.
So-
No spin + no dimples: No lift
Spin + no dimples: NO lift
No Spin + dimples: No lift
Spin + Dimples: lift (via magnus, not bournulli)
This, of course, is well out of my area though.
But Chauncey said pretty much the same thing as you. The hole had to be small, on the curved bolt face, at the base base, aimed between the ball and bottom of barrel.
He have to be careful, since we are talking about 2 seperate areas:
What happens in the gun. (ie via CooperT, GalataticZ, Flatline/Apex,Undertow, Alien, etc)
What happens in the air. (ie paintball seam, fps, trajectory, etc)
