21 shots @ 26.4 fpe (av w/ 21.1gr Kodiak's) on high
64 shots @ 17.6 fpe (av w/ 14.3 gr CP's) on low
with home made adjuster, spring guide and cut down hammer spring.
Sorry, I don't have numbers without the HDD, but I know they where lower.
With the power on low it seems like all day before I have to recharge and very backyard friendly since I made a simple LDC.

the numbers would be with out the adjuster, spring guide and cut down hammer spring?

Unmodified, I got about 30 shots, av 800 fps (780 - 820) w/ 14.3 CP's. A pretty large spread. I also put in a Big Ed adjustable sear and polished the hammer. No changes to the valve. The standard deviation is now less than 4 fps on high (over 21 shots, 2100psi - 800psi) and about 19 on low (over 64 shots, 2000psi - 800psi).
I also added a second barrel band. Very accurate, yesterday was shooting a Gamo field target (squirrel) in the yard @ 20yds and put CP's through a 13mm hole over and over. I am very happy with the Disco and it has become the 'go to' gun.
