Carl Quick's LiteWieght 2240
So for about the last 24 months, I've had her on a serious diet. Now I am happy to
report that she lost nearly 13 ounces and is feeling so much better. And let me
say one thing, when I pick her up with one hand now she is light as a feather.
Well, almost a feather.
Things I have done so far:
OEM main tube was lightened by me.
Barrel is OEM and trimmed down by me.
Main tube plug is made of Delrin by me.
Gas cap is aluminum, comes from HPA and bored out by me.
Hammer is made from Delrin by me with a modified 1701P striker.
Valve is an aluminum Disco rear end with a brass Pro-Top by Anthony.
Trigger grip frame is aluminum by Bluefork Design and then hogged out by Gregg.
Front barrel band is aluminum, made by Anthony, drilled by Rich and milled by me.

Restrictive transfer port.
OK..here is the data. Same gun, same valve, same everything EXCEPT striker springs were swapped. As striker energy increased, the sweet spot pressure also increased.
But the shot count stayed the same.
10 shots from 620 590fps = 605fps averqage / 11 foot pounds
10 shots from 650 620fps = 645fps average / 12.5 foot pounds
10 shots from 675- 645fps = 660fps.average / 13 foot pounds
SO, If I want a 12 foot pound gun....would running at the higer pressure level and restgricting the transfer port (so that the energy level was at 12 foot pounds) increase the shot count...or not?

- I (mostly) agree with Bob. Higher pressure and striker energy... - Steve in NC on Jun 25, 2012, 10:38 PM
