Minimum Speed for .22 cal Diabolo pellets?

[mtbdrew]

I've tried searching this put everything comes up with max speed not minimum. Just wondering if there is a minimum speed they need to travel to achieve stable flight?

Actually tried everything from 14.3 to 22 grn pellets in my new .22 cal XS46U that was converted to the 600 fps Crosman gas ram. Couldn't find any pellet that would group consistently. Tested over the chrony with best result for Kodiak HPs in 18 grn of ES 4.2 the worst spread was only 20 with CPHP 14.3 grn. So new the gas ram was giving consistent pressure but at 40 yards looked like shotgun pattern. Finally swapped the low power for a regular powered Crosman gas ram and even the CPHP are giving good results at 40 yards.

I don't have a minimum for you, but it's under 300 fps with quite a few pellets in .177 cal.... or at least that's what the grasshoppers in my back yard would tell you.... Mind you at that velocity you don't shoot much over 20 yards....
