Cci quiet semi auto - will it cycle a semi auto rifleShow more

I was very skeptical about a low velocity and very quiet 22lr ammunition in a "fully" semi-auto rifle so I hade to try this new ammo from cci called CCI quiet semi-auto! I have tried Cci quiet 22 in a semi auto rifle before and it just becomes a single shot straight pull action rifle. the low power from the slow sub sonic ammunition does not have enough energy to reliably cycle the action on all of my semi-auto 22 lr rifles. so what's the difference? this ammo uses a heavier the normal projectile. the bullet itself is 45 grains compared the the Cci Quiet 22 which uses a 40 grain projectile. so what's the difference other than the 5 extra grains of bullet weight? watch this short scientific video to find out!!!
