My spring and barrel tests
I shot 10 times over a chrony with all three of my barrels with the same gray spring in my gun. Then I changed springs, shot 10 times again with the barrels and here is what I found.
10 inch Dye, porting just on the end, 8.5 inches to port
12 inch Dye UL 7 inches to the port
14 inch Dye SS 7.25 inches to the port
Gray spring
10 12 14
270.4 273.6 262.4 10 shot ave.
280 292 273 Hi shot
254 261 254 Lo shot
Gold spring
10 12 14
292.7 305.2 271.0 10 shot ave.
315 325 315 Hi shot
231??? 287 250 Lo shot
Now I realize that there may be a slight diff in barrel size, but for the most part they are supposed to all be the same size bore.
My question would be this...... If I use the Gold heavy spring, and turn down the air, won't I get better efficiency in theory???
I may cover up the porting and try the same thing later. What are your thoughts?
It seems I need to change out all my orings too. Atleast the reg seat o-ring.
