I'm also looking at running a reduced velocity for reballs. Any suggestions for setup to run ~225-250 fps while maintaining best efficiency? The vast majority of my use comes in a basement with reballs so that is my first priority to start.
editing my set-up into here b/c i know at least one person will ask:
--Engine: Eigen, NDZ ULP can, stock sleeve, stock HE guide fitted with 12/70 buna o-rings (red Lurker rings were extremely loose fitting and actually caused more stiction than the buna's)
--Electronics/noid: Humph noid attached to a hater board running 14 ms dwell
--IPR mod too
I have to shoot 250 fps becuase I play indoors on a pretty small field, my Eigen runs 140 psi, 14 ms dwell. I shot half a case on Friday, and only had to fill my 45/45 once. I went with about 2.5k worth of air, emptied it and got it filled to 4k once, now it's at 2k. These are just very rough estimates, but if i shot 4.5k of air for 1/2 case thats 4.5 psi/shot. 4500psi/4.5psi per shot = ~1000 shots from a 45/45. Or ~1500 from a 68/4500. Pretty damn good numbers, but do take into consideration I'm playing low fps, it'd be a touch lower @ 280, but nonetheless I think they are still some of the best efficiency numbers posted yet. I think the numbers are only going up because I don't think it's going to fully break in until at least 5 cases thru it, each case i can drop the dwell ~2 ms. I'm targeting 140 psi/10 dwell
I'm going to be playing at least 2 or 3 times this week so I can keep better track of the numbers and get a better calculation if anyone is interested.
