vindicareassassin and i derailed a bit in the ER-hop thread so we figured a new thread about custom nozzle-designs are in order!
Have anyone made any extensive testing or are you all running stock profile?

-Copy of the post i mentioned in the ER-hop thread.
Here's a kinda sketchy explanation of how i lathe my nozzles - dont seem to do much when you're in the 350fps range but once you get closer to 500fps and above this REALLY helps with both consistancy and bb-placement between the rubber-lip and inner barrel.
first 2 pictures are of a standard nozzle and how it looks inside
Numbers correspond to the numbers on the image below.
1. flat surface against flat surface, creates non constant-wear and tear on the hopup rubber since it's flexing before snapping over to the 40 degree angled part of the nozzle.
2. Once the nozzle is pushed in as far as the actuall rubber will alow you're not really using all of the buckings available contact-surface-
3. Here is how i shape my nozzles, when the bb passes the buckings seal-ring the nozzle smoothly glides into the "chamber" and actually pushes the bb further into the barrel making it seated within the barrel rather than centered on the nozzle.
4. here is how it all looks when compressed, note the ammount of contact surface compared to the top view. AND last but not least, there's an actual STOP to the nozzle, creating a constant seal and constant BB-placement in the chamber every time =)
if we can find consistancy in the way every part moves every cykle i figure this must be one of the more important ones!!

This does (needless to say) require that the tappetplate is modded for extra travel into the rubber.
