25 cal Bigboy Caiman


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.
