We have been experimenting on a .25 caliber Big Boy Caiman with a 20
inch HW barrel for the export market. Noli just reported what he's getting so far:
Pellets: Beeman FTS (19.5g approx)
1st Shot: 904.9fps
20th Shot: 908.8fps
30th Shot: 908.22fps
40th Shot: 900.1fps
50th Shot: 896.0fps
60th Shot: 909.1fps
70th Shot: 890.0fps
Shot to shot dev: 4 - 6 fps
Starting fill: 3,100 psi
End Fill: 2,000 psi
Now, to also make a related theory, we expect the new 19 grain .22 cal Hystans to perform similarly, but with more shots of course because of the added pressure created by the smaller volume of the .22 cal barrel.
Updated, pics up.
