At what range are you placing the gelatin block for expansion tests? Are these pellets/slugs at 800++ FPS at reasonably normal hunting distances?
For clarification:
(1) I have not conducted these tests, only summarized what I found online.
(2) The velocity that is critical to expansion is not the muzzle velocity but the impact velocity.
Depending on the projectiles BC, the ranges at which an impact velocity of 800fps can be maintained varies wildly. E.g., calculation with ChairGun of three .22cal HPs, shot with a 36FPE gun:
● H&N Crow Magnum (18.21gr) published BC 0.022 (GA) (though likely lower for a "flying ashtray" at such high velocities)
➧ MV=944fps | IV=800fps at 24 yards
● H&N Baracuda Hunter Extreme (18.52gr) published BC 0.026 (GA)
➧ MV=936fps | IV=800fps at 27 yards
● FX Hybrid slug (22.00gr) published BC 0.080 (G1)
➧ MV=858fps | IV=800fps at 40 yards
Cheers,
Matthias
